Windows VM Randomly Network not Working (no internet)

[Bidi]

Hello Guys,

I have a problem with all Windows VMs hosted on dedicated server with Proxmox 6.4-15.
On the server ar only those 10 VMs with Windows 10, 2019, 2016 Randomly installed.

The server is fresh installed like 2-3 mo ago, we whanted to change the server because was an old r410 one having like 5years and whanted sompting with mo cores and ram.

The problem is, all the VMs Randomly network stops working, lets say after rebooting them after 3-4 days 2-3 not working after another 3-4 days another 3-4vms other ones not working and it makes like this since we installed the server and we dont know what to do.

On the old servers the VMs was having like 5 years never made this problems, never, on this one the new dedicated server we have this problem.

I truly dont know what to do with them, we even check network, changed network to virtio, made fresh installs of the vms, changed network cable, changed ips, still the same :|

I login to the VM, disable and enable network and after works

I have the same issue. I have 3 Dell R340 servers, each running Proxmox 8.1.3. Only VMs with Windows operating systems experience internet connectivity issues upon startup. Sometimes, disabling and re-enabling the network card helps, while other times, it is necessary to remove and reinstall it in the device manager. VMs with Linux operating systems work without any problems.

dedicated server with Proxmox 6.4-15.

Proxmox VE 6 is EoL, so I recommend upgrading PVE and then see if it still occurs. If necessary, also check the firmware from the server.

OK. And what with my 8.1.3 ?

@lukasz.w i would recommend you open a new thread and not take over another one. Just because the symptoms are similar doesn't mean it's the same problem. It can be, but it doesn't have to be.

The best thing to do is to open a new thread and post all relevant information there such as software versions, cluster description, VM config, special configurations, etc. pp.
