I Cannot Connect to My Proxy — What Should I Do?

Quick answer: Check your credentials for copied invisible spaces, ensure your IP is correctly whitelisted, or restart your router to clear stuck network sessions.

Step-by-Step

  1. Re-copy your credentials — Use the copy icon on your ProxyPorts dashboard. Do not manually select and copy text, as this often picks up invisible spaces.
  2. Check your authentication method — If you use IP Whitelisting, confirm your current public IP matches what is saved on the dashboard. If your IP changed (common with dynamic IPs or mobile hotspots), update it — but remember the 30-minute cooldown between changes.
  3. Restart your router — Power off your router for 30 seconds, then power it back on. This clears stuck NAT sessions and stale DNS cache.
  4. Wait 30 minutes to 2 hours — Some connection issues are caused by stuck sessions on the network side that clear automatically.
  5. Test with curl:
    curl -x http://USERNAME:PASSWORD@HOST:PORT https://httpbin.org/ip
