Hello, i am new to proxmox and virtualisation. I have my proxmox server running with 4 ubuntu server VMs and today it just randomly went out. I can not acces the GUI, ssh or use any of the services. I tried pinging both the router and 126.96.36.199 but it could not reach them. The laptop it is running on has an ethernat cable that i tested and it is working. Please help me if you have any ideas.
