Three causes cover most failures. Work through them in order, and test the proxy outside GenLogin before you change anything else.
Cause 1: the proxy type does not match. GenLogin offers HTTP Proxy, Socks4 Proxy and Socks5 Proxy in the profile, and the connection on your side was created as HTTP or SOCKS5. Our protocol tests of 4 November 2026 showed that a credential created as HTTP failed over SOCKS5 on port 3333, while one created as SOCKS5 also worked over HTTP on 2222. So when in doubt, choose HTTP and port 2222.
Cause 2: the line was pasted wrongly. A missing or swapped part, a space at the end, a port from a different connection or a password with special characters copied by hand is enough. Copy the whole host:port:user:pass line from My assets instead of typing it.
Cause 3: the IP or your network. The lease may have ended, a VPN or a system proxy on your computer may be in the way, or a firewall may block the port. This is the one a curl test separates from the other two.
Open My assets, copy host, port, username and password, and run the curl command in the next block on the same computer. It should print the proxy's IP and country.
Expected result JSON with the exit IP of the proxy.
Before continuing If curl fails, stop here: the problem is the details, the lease or your network, not the profile.
The connection card shows HTTP or SOCKS5. Set the GenLogin proxy type to the same one, with port 2222 for HTTP and 3333 for SOCKS5. If you are unsure, use HTTP on 2222.
Clear the proxy fields in the profile, paste the host:port:user:pass line from My assets again and press Check Proxy.
In My assets, check that the IP has not reached its end date. Auto-renew is optional and set per IP, so an IP with it off ends on its date.
Turn off any VPN and any system-wide proxy on the computer while you test. From mainland China, open Proxy302 Fast Connect before you use the proxy.
Once the check passes, open https://ipinfo.io/json in a profile window and confirm the country matches what the account expects.
Expected result The IP and country of the proxy.
# 1) HTTP proxy (port 2222)
curl -x "http://LOGIN:PASSWORD@HOST:2222" https://ipinfo.io/json
# 2) SOCKS5 proxy (port 3333); socks5h lets the proxy resolve the host name
curl -x "socks5h://LOGIN:PASSWORD@HOST:3333" https://ipinfo.io/jsonExample only: replace LOGIN, PASSWORD and HOST with the values from My assets; percent-encode special characters in the login.
| Item | Port | If the GenLogin type does not match |
|---|---|---|
| Static ISP, rented per IP | HTTP 2222, SOCKS5 3333 | Both protocols connected in our test of 4 November 2026 |
| Static ISP billed per GB | HTTP 2222, SOCKS5 3333 | Works only over the protocol it was bought with |
| Rotating residential | HTTP 2222, SOCKS5 3333 | A credential created as HTTP failed over SOCKS5; one created as SOCKS5 also worked over HTTP |
| Datacenter, rented per IP | HTTP 2222, SOCKS5 3333 | Each IP has one protocol, chosen at purchase |
Source: Proxy302 product facts file (protocol tests of 4 November 2026, one account, ipinfo.io through proxy.proxy302.com). The console marks per-GB assets as HTTP only or SOCKS5 only.
Check Does curl with the same details work? Is the type HTTP or SOCKS5 as on the connection card?
Fix Fix the type and port first, then paste the whole line again.
Stop when If curl fails too, do not keep editing the profile; look at the lease and your network.
Check Did the IP reach its end date, or did your computer's VPN or system proxy change?
Fix Check the end date in My assets; renew if needed, then retest.
Check Are you pasting into the right profile, with no space at the end of the password?
Fix Clear the fields and paste the line again; choose HTTP on 2222 if SOCKS5 keeps failing.
Check Is this the IP you bought for this profile?
Fix Open https://ipinfo.io/json in the profile and compare with the country in My assets.
For a profile that stays signed in to the same account, a static ISP IP does not rotate during the lease: US$0.50 for 1 day or US$7.99 for 30 days (about US$0.27 a day). Give each profile its own IP and keep the profile's timezone and language in line with the IP's country.
There is no free trial; the smallest purchase is one IP for one day. If an IP stops working, write to Support with the order number and it is reissued.
Usually the proxy type does not match the protocol, the pasted line is wrong, or the IP or your network is the problem. Test the same details with curl to tell which.
The one that matches the connection card. If you are unsure, HTTP on port 2222 is the safer choice, because a SOCKS5 credential also worked over HTTP in our test.
In the pages we read on 14 November 2026 it does not, so this guide does not quote them.
Check its end date in My assets, then write to Support with the order number; a failed IP is reissued.
Choose Your Proxy on GenLogin's Network tab, paste a Proxy302 IP and click Check Proxy. With docs screenshots and the discount code.
Set up a proxy in AdsPower, BitBrowser, GoLogin, Kameleo, Hidemium or GenLogin: one IP per profile, where each field goes, and what a failed proxy check really means.
The ERR_PROXY_CONNECTION_FAILED error appears in Chrome and Edge when the browser cannot establish a connection with a proxy server.
When a proxy won't connect or is slow, check six things first: address, port and type, login and password, one proxy app only, the antidetect browser port, the exit IP.
HTTP 407 Proxy Authentication Required comes from the proxy server, not from the website you are trying to reach.
Official documentation · Confirmed on:
Read on 14 November 2026: the proxy type list in a profile is Local IP, HTTP Proxy, Socks4 Proxy and Socks5 Proxy. The pages we read (create profile, network, location, FAQ index) describe no proxy error messages and no failure causes, so this guide does not quote any GenLogin error text.
The page text is short and the form fields are shown only in screenshots.

Product facts file, tests of 4 November 2026 through proxy.proxy302.com with ipinfo.io: a rotating residential credential generated as SOCKS5 also worked over HTTP on 2222, one generated as HTTP failed over SOCKS5 on 3333; per-IP static leases connected over both protocols; per-GB static tokens connected only over the protocol they were bought with.
Results are from one account on one day; the console marks per-GB tokens as HTTP only or SOCKS5 only.
