How to Set Up a Proxy in an Antidetect Browser (and Fix "Proxy Check Failed")

One IP per profile, the four fields in the right place, and the real reasons a proxy check fails — including the error codes our own gateway returns.

ProductStatic ISP proxyA dedicated home-broadband IP that stays the same for your whole term

WebRTCFollow or replace with the proxy IPOtherwise WebRTC can reveal your real public IP

The button at the top opens static ISP proxies for social accounts. Our social presets start with SOCKS5 and our store presets with HTTP; you choose the protocol when you buy, and the asset keeps it.

Add a Proxy302 proxy to a profile

  1. Get the IP

    Buy one static ISP IP per profile and pick the country of each account. From mainland China, first run the helper tool from Connect → Helper tools in the console.

  2. Copy all four fields

    In My assets open the proxy and use Copy all: host, port, username and password. Rotating residential proxies use the gateway proxy.proxy302.com — port 2222 for HTTP and 3333 for SOCKS5.

  3. Create the profile

    Choose a custom proxy, set the type to match the asset and paste the fields. BitBrowser, GoLogin and GenLogin also accept host:port:username:password in one line.

  4. Run the browser's proxy check

    Most browsers in the table below have a check or test button — save the profile only after it passes. In Huayang, open a profile that uses the pool and check the exit IP instead.

    Expected result The check shows an IP in the country you bought.

  5. Confirm inside the profile

    Open the profile, visit ipinfo.io and run a WebRTC leak test. The IP must match the asset and no second address may appear.

"Proxy check failed": what it really means

The check fails straight away

Check Does the proxy type (HTTP or SOCKS5) match the asset? Did you paste all four fields exactly, with no space or scheme in the host field?

Fix Copy again with Copy all and set the type shown on the asset. AdsPower names a protocol mismatch and entry mistakes among the main causes.

407 or "CONNECT tunnel failed, response 407"

Check That is our gateway refusing a missing or wrong username or password — confirmed in our own test on 18 October 2026.

Fix Use this asset's credentials; do not reuse an old or deleted asset's password.

"User was rejected by the SOCKS5 server"

Check The SOCKS5 port refused the credentials, also from our test.

Fix Check the username and password, or switch the profile to HTTP if the asset shows HTTP.

Timeout from mainland China

Check Is the helper tool running? Networks in mainland China cannot reach overseas proxies directly.

Fix Open Connect → Helper tools, start it, then run the check again.

The check passes, but the profile shows your own IP

Check Is a VPN, encrypted-connection extension, antivirus or firewall interfering? AdsPower names these as causes.

Fix Turn them off for the test, remove conflicting extensions from the profile and check again.

It worked yesterday, fails today

Check Has the asset expired, or has the line's traffic or the wallet balance run out?

Fix Renew the asset or add traffic, then check again. Expired or disabled assets cannot connect.

Common questions

Can several profiles share one proxy?

They can connect, but every platform then sees the same address behind all of them — which defeats the point of separate profiles. Give each profile its own IP.

HTTP or SOCKS5 in an antidetect browser?

Either, as long as it matches the asset. Our social presets start with SOCKS5 and our store presets with HTTP.

Static or rotating proxies for antidetect profiles?

Static ISP for any profile that stays logged in. Rotating residential only with a sticky session, for short tasks that do not need the same IP tomorrow.

Which antidetect browsers work with Proxy302?

Any that takes an HTTP or SOCKS5 proxy with a username and password. We have step-by-step pages for AdsPower, BitBrowser, GoLogin, Kameleo, Hidemium, GenLogin and Huayang.

Why does the IP check pass but WebRTC shows another address?

WebRTC traffic can leave outside the proxy. Set WebRTC in the profile to follow or replace with the proxy IP and test again.

Account setups by platform

Social media management

Static ISP proxies for TikTok, Instagram, Facebook, X and 7 more networks: one dedicated IP per account, and where each network is blocked.

TikTok proxies

TikTok proxy for creators, sellers and agencies: one static ISP IP per account in the market it posts for, SOCKS5 or HTTP — for TikTok on the web and on iPhone.
