Error 404 in callback after successful SAML authentication

I have Gitlab CE Omnibus (v14.9) as a Docker container and I’ve been trying to configure SAML authentication via Okta provider. The issue is that, after a successful authentication I get redirected to Gitlab and a 404 error is displayed. I couldn’t find anything in the logs that would help with this.

Any help with this would be highly appreciated.

This is fixed. The problem was not on Gitlab side but on Okta side (incorrect audience URL).
