Keytab issue with F5 SSO for Kerberos Authentication issue

[Öznur006]

Hello, We publish our confluence page via F5 and at the same time we use Kerberos authentication method as SSO. For security reasons we changed the encryption method used in the keytab file and uploaded the keytab file to F5. After this change, confluence authentication did not work. I see a log like this in F5's APM logs. Does anyone have information or suggestions on this subject? logs:

This is a very specific problem and there obviously won't much support here. I suggest you open a support ticket with Atlassian for the guidance/feedback.
