[SOLVED] network loss

[l86]

Hi,
after upgrade proxmox to v7, when I reboot my server the network is Ok, and 20 minutes after, the network is lost, but just for the ssh and GUI access. The network for VMs are ok.

I checked Network interfaces on the IPMI connexion, and there are OK.
I checked ping on my gateway and there is ok too. In any case, it'is impossible ping IP addresses on the net.

My server is hosted at OVH. I have made upgrade 6.4 to 7.

If I reboot my server, the network is ok for 20 minutes.
Logs before down:
