If the rotating residential proxy cannot be connected, do not modify all parameters at the same time. It is recommended to check one by one according to network, traffic, parameters, authentication, protocol and target website response.

Problem 1: Connection failure or timeout

1. Confirm that the machine or server can access the Internet normally.
2. Confirm that the network environment that can access the backend and proxy gateway has been prepared in the network environment of mainland China.
3. Check whether the host and port are copied completely.
4. Switch to the background cURL example for minimal testing.
5. If it only fails with a certain tool, check whether the tool supports account and password authentication.

Question 2: Authentication failed

1. Click "Copy Username" and "Copy Password" again.
2. Make sure there are no extra spaces, line breaks or Chinese symbols when pasting.
3. The confirmation tool did not fill in the username and password positions backwards.
4. If you have just reset the credentials, replace the old credentials in all tools simultaneously.

Problem 3: IP regions are inconsistent

• Different IP databases update at different speeds, and the displayed results may be different.
• It is recommended to use multiple IP query websites for cross-validation.
• Confirm that the country, city, and region selected in the backend are not retained as default values.
• If the business is strongly dependent on a certain city, first test the availability with small traffic.

Problem 4: Data consumption is too fast

• Check whether there is a script or the browser continues to run in the background.
• Reduce concurrency and reduce failed retries.
• Turn off loading of images, videos and unnecessary large resources.
• Check the "Traffic Usage" and check it against the task running time.

Problem 5: Slow or unstable speed

• First use cURL to do a minimum test to distinguish proxy problems from business tool problems.
• Change the region or gateway option before testing again.
• Reduce concurrency and lengthen the timeout.
• When the target website itself is slow or the risk control is strict, the proxy speed will also be affected.

What to prepare before contacting support

• Product type: rotating residential proxy - GB.
• Question time, selected region, agreement and statute of limitations.
• Use tool name and error screenshot.
• cURL Minimal test results.
• Do not send full passwords, full API URLs, or full proxy strings to public channels.
