SSH and web GUI not reachable

[RomainGx]

Hello everyone,

I have set up my proxmox environment a few days ago and it was working very well since yesterday: it suddenly became unreachable from SSH or web GUI.
I still can connect directly on the host.

I have found similar threads on this forum but I couln't make it working so far
Can someone help me please?

Here are some information in screenshots. Please note:
- In a thread someone asked for the status of the `sshd.device`, but I don't know what it is, and if the cause of the problem would be that it is inactive (dead)
- I had a cyclic error on a custom service: gdrive.service, so a file system failed to create because rclone finds the token should be expired. But `systemctl list-units --failed` did not report errors. So I tried stopping the service and now it displays an error.
Can it be this file system failure that cause the problem? Or it is more probably a consequence of the network error?

Did you try to ping 192.168.1.80 from another machine?
PVE is updated to the latest 8.1.4 version (some realtek NICs like r8168 will crash with PVE8.0)?

Yes it is the same problem from another PC.
I don't remember the exact version I will show tomorow. But I installed it 3 days ago so I guess I have the 8.1.4

Hi!
I confirm I have version 8.1.4 of pve-manager

I just see that my gateway (192.168.1.254) is not reachable from proxmox.
So proxmox seems to be "out of internet"

I can see it in /etc/resolv.conf
But I don't know why I can't access it from proxmox, while I can from my PC

Good news, it's working today!
But this worries me a little bit: why could it be down so long?
