SSH connection closed to PVE


Aug 22, 2020
Hi all,

I have a strange issue.
I have a ProxMox 6.2 installation that I connect via ssh by Putty on my machine Win10.
But if on the same machine i try to connect via ssh from a VM like ubuntu or via ssh console of Chrome or via Terminus on my phone the connection is refused.

Why with Putty goes without problems and all the other connection it's refused?

I'd like to ask for some more information before being able to tell that for sure.

can you please elaborate the network situation/setup a bit?
Single "dumb" switch where all is connected together, or is it a more complex setup? (VLANs, multiple switches, routing, ...?)
Do you use a firewall, either ours on the Proxmox VE box or one on the gateway?

Can you ping the Proxmox VE box from those clients?

VM like ubuntu

So the VM is on the same Proxmox VE box you're trying to connect to?
Yes of course, I give you more information.

The network situation is not complicate, there is no vlan.
It's only a bond on 2 eth cards, that's all.

I use a firewall on the gateway (I have a similar configuration (same fw, proxmox etc.) by another customer and all is working without problems).

The VM with Ubuntu is on my pc, where I have putty to connect to ProxMox VE.
