502 Bad Gateway

Hello, @dimu505.

You can always use your Personal Lists of your website to permanently allow any IPs, networks, email addresses and other entries. I believe in your case, just to make sure, the company’s network could be added. The guide is here:

Also, your logs should contain all hits and blocks too:

Did it help you?

Thanks for the reply! The manager of hosting decided to move away from Clean Talk without testing the solution.

Thank you for letting us know.

If you decide to return to using our services, please contact us via our private Ticket System: https://cleantalk.org/my/support/open.

We will investigate what causes the errors to appear.
