Broken pipe 596 Error

[iknowledge]

I am facing a Broken Pipe 596 Error. I have a cluster of 4 Proxmox servers.
Due to the Broken pipe (596) error, I am not able to access the GUI of one of the Proxmox servers.

root@vm4:~# pveversion
pve-manager/8.1.3/b46aac3b42da5d15 (running kernel: 6.5.11-7-pve)

I did a lot of trial and error and guess what, I was able to fix this issue by running the following commands:

apt install corosync-qnetd

apt install corosync-qdevice

pvecm qdevice setup <QDEVICE-IP>

Generating a new SSL did it for me

1) openssl req -new -newkey rsa:4096 -nodes -keyout /etc/pve/nodes/$(hostname)/pve-ssl.key -out /etc/pve/nodes/$(hostname)/pve-ssl.csr
2) openssl x509 -req -days 3650 -in /etc/pve/nodes/$(hostname)/pve-ssl.csr -signkey /etc/pve/nodes/$(hostname)/pve-ssl.key -out /etc/pve/nodes/$(hostname)/pve-ssl.pem
