GoLand provides its own storage for trusted certificates. Use this page to manage this storage.
Accept non-trusted certificates automatically
Select this option if you want non-trusted certificates (that is the certificates that are not added to the list) to be accepted automatically, without sending a request to the server.
Add a trusted server certificate to the list. Select the certificate file in the dialog that opens.
The certificate file should have an extension .crt, .cer or .pem.
For a trusted certificate, the certificate information is shown in the lower part of the page.
Remove the selected trusted certificate from the list.
