Cannot access VM via the console if I change the SSH port.

[newbprox]

Hello,
I changed the ssh port of my vm and now the console cannot connect to the VM anymore through the proxmox web gui. Is there a way to fix this besides reverting to port 22?

the ssh port inside the vm has no relation to the browser console at all... or what exactly do you mean?
can you post the vm config ? (qm config ID)

Thank you for your help. Here is the config ID

boot: order=scsi0;ide2;net0

Let me give more context. In my proxmox cluster I changed all my VMs and Nodes to key based authentication only and changed the port from 22 to a different one. Now since I did that, I cannot use the novnc console (the built in one on the proxmox console) to access the VM's anymore....and I can only access the Node console if I am at the same ip address (gui). If I try to access node 2's console from node 1's ip web gui, it says "ssh: connect to host 192.168.1.30 port 22: Connection refused" I appreciate your help. I LOVE proxmox and think it is wonderful.

ok that does it make it clearer

if you use a non-standard port for ssh, you also have to edit the '/etc/ssh/ssh_config' (not sshd_config) to use the other port. this tells the ssh client which port to use by default
you can ofc also limit it to the pve hosts, just check the man page ('man ssh_config') for how to do that

Exactly what I was looking for. Thank you! I looked up 0FC but I’m not sure I quite understand. When I search ofc and ssh I get random references towards obfuscating ssh. Am I on the correct track?

I believe "ofc" in this case stands for "of course"
