Troubleshooting

Proxies not working: a practical troubleshooting checklist

Good troubleshooting moves from simple to complex: first prove that the proxy connects, then check country, protocol, mode, software and only after that analyze the target site.

Short answer

Start with basic connectivity and the visible exit IP, then move to the target site and software. This separates proxy issues from account, fingerprint and application problems.

What you should understand

  • Do not start with the target platform if basic connection is not verified.
  • Compare browser and main software: different errors often point to the client.
  • Remove extra filters to see whether the pool was narrowed too much.
  • Record time, country, mode, error and sample proxy for repeatable checks.

SOCKSFIVE settings that are actually relevant here

SettingWhen it mattersWhat to keep in mind
Protocolwhen software does not connectcheck SOCKS5/HTTP(S) and the proxy line format
Authenticationfor login/password or IP authorization errorsverify bound IP, username and password
Country/typewhen the issue happens only on one targetcompare the same workflow on another type or country
Sticky/rotationwhen errors appear after IP changesuse stable sessions for accounts

Practical check order

  1. Check basic connectivity and the external IP before the complex workflow.
  2. Change only one parameter at a time: country, type, blacklist or sticky/rotation.
  3. Compare results on the same website, account and test window.
  4. When contacting support, include the exact error text and connection parameters.

Practical example

Troubleshooting becomes fast when each test answers one question. “Does the proxy connect at all?” is one test. “Does the country match?” is another. “Does the software support this protocol?” is a third. If everything is mixed, the customer gets chaos: it is unclear whether the issue is login, port, DNS, target site or account. The checklist separates the problem into testable layers.
