Static proxy connection failures are commonly caused by incorrect settings, expiration, the source network, or target-service restrictions.
Key points
- Confirm the IP status and validity period in the proxy list.
- Check the host, port, protocol, and proxy connection credentials.
- Test with another proxy-capable tool to rule out application settings.
- Test other sites to determine whether only one target is restricted.
- If the IP has expired and no renewal action is available, purchase a new IP.
Note: Monitor the expiration time in the proxy list and check whether a renewal action is available before expiration.
