A  bit puzzled here.

Does /etc/pve/.members matches the output of pvecm nodes as you said in
your initial mail ?

The .members file is generated by the pvestatd daemon, so have a look
with journactl -u pvestatd if you see here something suspicious

journalctl -u pve-cluster and journalctl -u corosync might help too.
