can you advice how we can investigate properly quorum problems ( nothing we found on forum on net give us answers ) , after upgrade from 5.x to 6.x we loss quorum almost every day, but omping looks works as expected, whole network is on ovs, before corosync 3.x and proxmox 6.x we never get this problem.

Best Regards,
please update corosync and libknet1 to the latest version available in the pve-no-subscription repo - it contains quite a few bugfixes.

Hope this helps!
Glad the issue went away! please mark the thread as 'SOLVED' so that others know what to expect.
