Today I upgraded my boxes to the latest version of Proxmox (pve-manager/5.4-5/c6fdb264 (running kernel: 4.15.18-13-pve)) and I got this error:
Code:
May 1 11:25:06 proxmox-node-1 pve-firewall[2565]: status update error: unable to apply firewall changes
May 1 11:25:16 proxmox-node-1 pve-firewall[2565]: status update error: unable to apply firewall changes
It is strange that I got this only on one of the nodes, the other node works like a charm. The node which generates these errors, acts as slave node on the cluster.
I tried to disable/enable the firewall, without success. The error still persists.
I also checked the security groups, but there is no security group with - dash character in their names. I have rules with _ in their names if this can be the problem.
So, can somebody help me to resolve this? I can attach any log if it's needed.
Thanks in advance.
