Strange problem with one node, server off but not

[Bidi]

Hello guys,

I wake up with one node d2 to be offline but not, i`m able to acces ssh, proxmox on boath servers, if i acces proxmox from d2 it shows boath nodes off, if i acces from d7 it shows only d2 off ...etc

Some lxc if i push start button i get the ct runing allready, some of them they dont, some of them they work, there is no strange traffic, no nothink, i dont even know what to do cuz is the frist time when i get this problem :|

Dose anyone have any ideas ?
Thank you
