![Uploading Screenshot from 2024-06-18 08-45-25.png…]() Hi,

I may have an issue with openshift-4-loadbalancer-ocp4.service after updating my hetzner from RHEL 8.10 >> 9.4. My 3 ocp KVM Servers are all up and running and after checking out the local coreos log(s) there most likely not in trouble.

Any Idea what that might cause and how I might solve that? Thanks

Ok, obviously with a LEAPP Upgrade from 8 to RHEL 9 the "AllowZoneDrifting" Parameter got set to NO. After setting it to "yes" again the LB is working again and I can access the cluster voa UI and OC again.

Command: sed -i "s/^AllowZoneDrifting=.*/AllowZoneDrifting=yes/" /etc/firewalld/firewalld.conf Restart FW afterwards.
