Connection issues when kerberos ticket is active

[faxm0dem]

We're having issues connecting to the daemon when a kerberos ticket is available.
This is happening since we upgraded the host running conserver from Centos7 to Centos8Stream, thus moving conserver from 8.2.1 to 8.2.2.

We are facing the same issues with 8.2.6 that have appeared overnight, without us modifying any configuration or restarting any services on Debian bullseye, which makes me suspect it could be an issue that occurs related to updates on the Kerberos server side?
