How to set up a proxy in Antik Browser: add it, check it, fix the errors

To add a proxy in Antik Browser, open Create Profile, choose New Proxy, pick Http/Https or Socks5 to match the port, paste the line as host:port:login:password and read the check under the field: flag, time zone and IP. Give every profile its own sticky session. Below: each step, ISP and mobile lines, bulk import and a fix per error.

Antik Browser keeps every profile apart: its own fingerprint, its own cookies and, once you add one, its own proxy. The proxy decides which IP address and which country the sites see. Antik needs one line with four values in it, and most "proxy not working" cases come from one of those four. The field names below are the ones in Antik Browser's own documentation and in its current window; the values come from the QuanticData endpoint generator, with a real check of a Ukraine line made on 24 October 2026.

What you need before you start

• Antik Browser installed, with an account. Its site lists downloads for Windows 10 or later and for macOS on Intel and M-series Macs, and a free trial of up to 7 days with 10 profiles. The current release is 1.20.0.
• A proxy plan. Residential Premium, ISP or mobile: all of them work in Antik Browser. The table further down says which one fits which profile.
• The four values: host, port, username and password. In the QuanticData dashboard they are under My proxies, on the plan's page, in the Endpoint generator.

The proxy formats Antik Browser accepts

Antik Browser reads a proxy as one line. Next to the Proxy field it shows a Supported proxy formats box with four layouts, and its documentation adds two extras:

• host:port:login:password: format 3 in the box, and what the generator gives with the output format host:port:user:pass.
• login:password@host:port and login:password|host:port: the same proxy with the login first.
• host:port: only with IP whitelist authentication, where the plan recognises your IP and no login is sent.
• The type in front: socks5:// at the start makes the line SOCKS5; a line with no type is read as HTTP.
• ::name at the end names the proxy in the list, and a link in square brackets after the line adds an IP change link (not needed with QuanticData).

The same QuanticData proxy in the layouts that matter:

# host:port:login:password (format 3)
residentialpremium.quantumproxies.io:8080:USER-country-ua-sid-p01-ttl-60m:PASS

# login:password@host:port (format 2, without the type)
USER-country-ua-sid-p01-ttl-60m:PASS@residentialpremium.quantumproxies.io:8080

# SOCKS5 on its own port, named in the Proxy list
socks5://residentialpremium.quantumproxies.io:1080:USER-country-ua-sid-p01-ttl-60m:PASS::UA 01

The login is the whole username string, with everything after the first dash: -country-ua picks the exit country, -sid-p01 names the session and -ttl-60m keeps it for 60 minutes. Copy it whole. A login cut at the first dash still authenticates, but the profile then leaves from a random country on a new IP at every request.

Residential Premium proxies in Antik Browser, step by step

1. Generate the line. In the QuanticData dashboard open My proxies, then your plan. In the Endpoint generator choose the Country (and a Region or City if the profile needs one), set Session to Sticky, set Session TTL (minutes) to at least the time the profile stays open, choose the Protocol and keep the Output format on host:port:user:pass. The Preview shows the line; Connection details shows the same four values one by one.
2. Open Create Profile in Antik Browser. On the Profiles tab click Create +. Give the profile a name, a folder if you use them, the operating system and a label, then scroll to Proxy. To change an existing profile, click the gear icon on its row.
3. Choose New Proxy. The other choices are Without a proxy and From List, the proxies stored on the Proxy tab.
4. Pick the type that matches the port. The buttons are Http/Https, Socks5 and Socks4: Http/Https for port 8080, Socks5 for port 1080. A line that starts with socks5:// carries its type with it.
5. Paste the line into Proxy. One line, no spaces, nothing after the password. Name is optional: a label like UA residential 01 helps in the Proxy list.
6. Read the check. Under the Proxy field Antik Browser shows the flag of the exit country, its time zone and its IP. The flag has to match the -country- in the login: our Ukraine line showed Europe/Kyiv, and the same session checked through ipinfo.io answered Bereznehuvate, Mykolaiv region.
7. Leave IP Change Url empty. With QuanticData a new IP comes from a new session ID in the login, explained further down.
8. Keep Add to proxy list ticked and click Create. The line is saved on the Proxy tab too, ready for From List in other windows. Start the profile: Antik's start page shows My IP and the country of the exit.

One sticky session per profile

An antidetect profile is meant to look like one person on one connection. A rotating proxy changes IP on every request, which is fine for scraping and wrong for a profile that logs in. A sticky session keeps one IP for as long as the session lives, and the session lives in the username, so the line never has to change once it is saved in the profile.

# profile 1: Ukraine, one session for a working day
residentialpremium.quantumproxies.io:8080:USER-country-ua-sid-p01-ttl-480m:PASS

# profile 2: same plan, its own session (never reuse p01)
residentialpremium.quantumproxies.io:8080:USER-country-ua-sid-p02-ttl-480m:PASS

# profile 3: Poland, open all day
residentialpremium.quantumproxies.io:8080:USER-country-pl-sid-p03-ttl-1440m:PASS

Three rules cover almost every case:

• A different session ID in every profile. Two profiles on the same line share one IP, which is exactly what an antidetect browser is there to avoid.
• A lifetime longer than the work. The generator accepts up to 1440 minutes, a full day. When the session ends, the next request gets a new IP, and a site can see that as a new login location.
• The country in the login. Without -country- the exit can be anywhere, and the flag and time zone under the field will not be the ones you meant.

With Session set to Sticky, the generator makes as many lines as the Quantity field says, ten by default, each with its own session ID, and Copy all or Download takes them out in the same format. One line per profile.

Which proxy type for which profile

Proxy type	In Antik Browser	Good for
Residential Premium	One sticky line per profile; country, region, city or ISP in the login; Http/Https on 8080 or Socks5 on 1080	Most profiles: home IPs in the country you choose, for example Ukraine residential proxies
ISP	Fixed IPs listed under Assigned IPs as IP:Port:Username:Password; one IP per profile; port 50100 for HTTP, 50101 for SOCKS5	Long-lived accounts that should keep the same address for months
Mobile	One sticky line per profile with -type-mobile in the login; Global, USA, EU or Asia gateway; HTTP 8080 or SOCKS5 1080; IP whitelist available	Phone-first platforms and accounts tied to mobile networks

For a wider view of why each profile needs its own address, see residential proxies for antidetect browsers. The plans themselves are on the pages for QuanticData residential proxies, ISP proxies and QuanticData mobile proxies.

ISP proxies in Antik Browser

An ISP line goes in like the others, with one difference: the IP is fixed. In the dashboard, Proxy endpoints, Assigned IPs lists one IP per line as IP:Port:Username:Password, which is format 3 in Antik's box. Choose the Protocol there first: HTTP / HTTPS lists port 50100, SOCKS5 lists port 50101.

1. Copy one line from Assigned IPs.
2. In the profile, New Proxy, pick Http/Https for port 50100 (or Socks5 for port 50101) and paste the line.
3. Name the proxy after the IP, for example ISP 01. The check under the field shows the IP of the line itself.
4. Leave IP Change Url empty: that IP does not change. Give the next profile the next IP, never the same one. Country pages such as Ukraine ISP proxies list where ISP IPs are available.

Mobile proxies in Antik Browser

A mobile line works like a Residential Premium one, with -type-mobile in the login and its own host. In the mobile Endpoint generator choose the gateway (Global, USA, EU or Asia), set Session to Sticky and pick the protocol: HTTP · 8080 or SOCKS5 · 1080. Mobile plans also offer IP whitelist authentication: add your IP below the generator and use the host:port list with no login, format 1 in Antik's box. Coverage by country is on pages such as Ukraine mobile proxies, and the use with antidetect profiles on mobile proxies for antidetect browsers.

To move an existing profile to a mobile line without opening its settings, use Antik's quick change: on the Profiles tab, the three dots next to Start, then Change Profile Proxy. The Update Proxy window has the same New Proxy and From List choices. Paste the line; with no type in front Antik reads it as HTTP, so keep port 8080, or write socks5:// before a port 1080 line. Leave IP Change Url empty and click Update.

Many profiles at once: the Proxy list and From List

For more than a few profiles, store the lines first and pick them later. Antik's Proxy tab keeps a list of proxies that any profile can take with From List.

1. Make the lines. In the generator, set Session to Sticky and the quantity you need, generate, then Copy all or Download.
2. Import them. On the Proxy tab click Create +. Under Import Proxy choose Text and paste the lines, one proxy per line, or choose File and drop a .txt file with the same lines. Add ::UA 01, ::UA 02 and so on at the end of each line to name them.
3. Check them. The Check imported proxy table lists every line with its name, protocol and port; Check tests each row before you save.
4. Save and assign. Create + stores them. In each profile choose From List and pick a different line every time.

Antik's Mass creation tab can also create a batch of profiles and hand out proxies to them in the order you give. If there are fewer proxies than profiles, its documentation says the proxies are used again, which puts two profiles on one IP: generate at least as many sticky lines as profiles.

A new IP without touching the profile

Antik's IP Change Url field is meant for providers that change the IP through a link; with a link saved, a Change IP button appears on the profile's row. With QuanticData Residential Premium and Mobile leave it empty: the IP is tied to the session ID in the login, so a new session ID, for example -sid-p02 instead of -sid-p01, is a new IP. Change Profile Proxy swaps the line, and the old line keeps working until its lifetime ends. ISP proxies are static addresses by design: one IP per profile, for months.

Antik Browser proxy not working: errors and fixes

A wrong value shows up in two places: the check under the Proxy field does not come back with the flag and time zone you expect, or the profile opens and its window shows Chromium's error page instead of Antik's start page. The most common one is ERR_PROXY_CONNECTION_FAILED: the profile could not reach the proxy at all.

What you see	Usual cause	Fix
ERR_PROXY_CONNECTION_FAILED in the profile window	A wrong host or port, or a network that blocks the port	Copy the line again from the generator's Preview; test the same values with curl from the same computer
No flag under the field, or pages do not load, with the right host	The type does not match the port: Http/Https on 1080 or Socks5 on 8080	Http/Https with 8080, Socks5 with 1080, or socks5:// in front of the line
The same, with the right type	The login was cut, a colon is missing, or a space came with the paste	Paste the line whole, in format 3, with nothing after the password
It worked yesterday, fails today	The plan expired or its traffic is used up	Check the plan in My proxies: status, remaining traffic, expiry date
Wrong flag or time zone	No -country- in the login, or Worldwide chosen in the generator	Generate the line with a country and paste it again
The IP changes in the middle of a session	The session lifetime ended, or two profiles share one session ID	A longer -ttl- and a different -sid- in every profile

One test outside the browser settles most cases in a minute. If this returns an address in the right country, the proxy works and the problem is in the profile's fields:

curl -x http://residentialpremium.quantumproxies.io:8080 \
  -U "USER-country-ua-sid-test-ttl-10m:PASS" https://ipinfo.io/json

If the same command fails on your network but works from another one, a firewall or your provider is blocking the connection to the proxy port.

HTTP or SOCKS5 in Antik Browser

Both work for browsing, and every QuanticData network offers both. Http/Https on port 8080 is the simpler choice and the one to start with. Socks5 on port 1080 passes any kind of connection, not only web pages, which matters for tools inside the profile that do not speak HTTP; the details are on the page for SOCKS5 proxies. Antik's third button, Socks4, belongs to an older protocol that carries no password, so it does not fit a username and password proxy. What breaks a profile is never the choice between HTTP and SOCKS5, only a type that does not match its port.

Before you run accounts

A proxy changes where a profile's traffic comes from, not what the profile is allowed to do. Keep to each platform's terms and to the law where you work, and use one profile, one session and one identity per account.
