AdsPower proxy not working

Last checked 2026-08-14

  • adspower proxy not working
  • adspower proxy failure
  • adspower proxy connection test failed

'adspower proxy connection test failed' appears in the completions as a query of its own, so an in-app test is part of how people arrive at this question. A test that answers pass or fail cannot say which cause it hit: the proxy can be offline, online but refusing your credentials, online and authenticating but blocking CONNECT, or working perfectly while a second proxy setting overrides it. All four collapse into the same failed test.

Every check below runs outside AdsPower on purpose. If a proxy works in curl and fails in AdsPower, the problem is the browser configuration. If it fails in both, the browser is not involved at all. That single split is what removes the ambiguity.

Replace USER, PASS, HOST and PORT with your own values in each command. Keep the single quotes: an ampersand or a hash in a generated password will otherwise be eaten by your shell.

Five-minute checklist

1. Check the credentials work at all

Establishes a baseline. A 200 here means the proxy, the port, the protocol and the credentials are all fine, and the fault is inside AdsPower.

curl -sS -o /dev/null -w 'http_code=%{http_code}\n' --max-time 15 --proxy 'http://USER:PASS@HOST:PORT' https://example.com

2. Separate "wrong password" from "not reachable"

Send the same request with no credentials. A 407 proves the proxy is listening and demanding authentication, so the host and port are right and only the credentials are wrong. A timeout or refused connection means the host, the port, or your network is the problem.

curl -sS -o /dev/null -w 'http_code=%{http_code}\n' --max-time 15 --proxy 'http://HOST:PORT' https://example.com

3. Check whether only HTTPS is broken

HTTPS through an HTTP proxy needs the CONNECT method. Some upstreams allow plain HTTP and refuse CONNECT, or have port 443 blocked on the exit. If this command succeeds while step 1 failed, CONNECT is your problem, not the credentials.

curl -sS -o /dev/null -w 'http_code=%{http_code}\n' --max-time 15 --proxy 'http://USER:PASS@HOST:PORT' http://example.com

4. Confirm the exit IP and its country

A proxy can be fully working and still be the wrong proxy. This is also how you catch a pool that silently failed over to a member in another country, which leaves the browser timezone contradicting the exit IP.

curl -sS --max-time 15 --proxy 'http://USER:PASS@HOST:PORT' https://api.ipify.org

5. Rule out IP allowlist authentication

Some plans authenticate by source IP, not username and password, so you need your own machine's direct egress IP, not the address the proxy would show. The empty --proxy value here is deliberate, not a typo: it overrides any http_proxy or https_proxy environment variable set on the machine and forces a direct connection. On a machine where one of those variables is set, a bare curl to this same URL would go through that proxy instead and hand you the wrong IP, which is the one number this check cannot afford to get wrong. Check the reported IP against the allowlist in the provider dashboard; if the plan is allowlist-based, the credentials you were given are decoration.

curl -sS --max-time 15 --proxy '' https://api.ipify.org

6. Read the handshake to see which layer fails

The verbose trace tells you whether the TCP connection, the proxy CONNECT exchange, or the TLS handshake is where it stops. That is the difference between a network problem, a permission problem, and a certificate problem.

curl -sS -v --max-time 15 --proxy 'http://USER:PASS@HOST:PORT' https://example.com 2>&1 | head -n 25

Which side owns the problem

OwnerCauseWhat it looks like
The browser Protocol mismatch in the profile An HTTP proxy entered as SOCKS5 cannot complete a connection at all, and a result that only reports failure does not name the mismatch. Check the protocol setting against what the provider actually sold you.
The browser A second proxy setting overriding the profile A system-level proxy and a profile-level proxy can both be active at once. When that happens the profile still reads as correctly configured while traffic leaves through the other one, so nothing you can see in the browser points at the real cause.
The browser Pasted credentials carrying invisible damage Trailing whitespace, a full-width colon from a Chinese-locale editor, or a line break inside the host field. curl and a browser input field do not necessarily tolerate the same characters, which is why step 1 sometimes passes while the browser fails.
The proxy Plan exhausted or concurrency limit hit The upstream still answers TCP and still authenticates, then refuses to forward. Nothing in the browser can distinguish this from a bad password.
The proxy CONNECT not permitted on the exit Plain HTTP works, every HTTPS target fails. Step 3 isolates this in one command.
The proxy Allowlist authentication, not credential authentication Your egress IP is not on the list, so the credentials are irrelevant. Step 5 gets you the IP to check.
Credential handling The same credentials in several hands at once When one host:port:user:pass string is shared with several people, the provider sees concurrent sessions from unrelated IPs and may throttle or block. From inside the browser this is indistinguishable from a broken proxy, and nobody can tell you who else is using that string.
Credential handling Rotated credentials still in circulation The password was changed on the provider side, but whoever received the old string is still using it. Every one of their attempts now looks like an authentication failure.

The same failure in other browsers

Vendor documentation only covers its own product. These are the phrasings the same underlying faults get in the other antidetect browsers.

BrowserHow it readsWhat differs
gologin gologin proxy not working Same underlying causes, same diagnosis order. 'gologin proxy checker' is a completion of its own, so a proxy check is something people look for there too - and any pass/fail verdict leaves the same gap: no layer information.
multilogin multilogin proxy check failed 'multilogin proxy check failed' is worded as a check result rather than as a site that would not load. A check and your real destination are two separate requests, so a failed check is not proof the proxy is unusable.
dolphin-anty dolphin anty failed to establish proxy connection Phrased as a connection failure, but 'dolphin anty proxy format' shows up as its own separate completion alongside this one, under the same search seed. That is enough to say the input format is worth checking on its own, distinct from reachability; autocomplete volume does not tell us how often either cause actually occurs.
octo-browser octo browser failed to get proxy data This one is genuinely different: it points at reading the proxy configuration, not at reaching the proxy. Do not treat it as the same fault.

What this page cannot fix

  • An upstream IP that the destination site has already banned. That needs a different exit, and we do not sell IPs.
  • socks5 upstreams. Our first release only accepts http and https upstream proxies.
  • Bandwidth caps, concurrency limits and throttling applied on the provider side.
  • A browser fingerprint that contradicts the exit IP. When a failover pool switches to a member in another country, the profile timezone and language do not follow. We warn about this; we do not rewrite your fingerprint.
  • Any part of AdsPower itself. We do not ship a browser.

If you hand these credentials to other people

Most of the causes above are diagnosable in one command. One is not: when the same host:port:user:pass string is in several hands, you cannot tell who is using which credential, so the same failure keeps coming back and every diagnosis starts from zero.

Proxy Bastion gives each person a separate, revocable, metered link instead of your proxy credentials. They never see the upstream address or password, and you can revoke one without rotating anything.
