Node out of cluster

[shan]

Hi,
Here is my situation:

2 hp servers 192.168.0.241 and 192.168.0.242

I installed proxmox on both servers, then I made the cluster on 242 and added 241 as a node, now for few days it was working fine then suddenly I see that when I enter from 241 I can see the other promox online and same the other way around I don't know why it's happening I tried restarting but no luck

Thank you
