Proxmox Backup no web access (8007)

Hi all,

Since today, my Proxmox PBS server is unavailable on a browser (connection refused)

I check proxmox-backup-proxy service, it's up.
When I do a netstat -natp | grep 8007, I have only :

tcp6 0 0 :::8007 :::* LISTEN 570/proxmox-backup-

There is no ipv4 listen port.

Of course its IP is pingable from my computer.

I tried to restart service, restart VM, but without success :/

Any idea ?

check with `ss -tlnp |grep 8007` (netstat has been deprecated for quite some time, additionally ss does output *:8007 for sockets with listen on both stacks (by not setting IPV6_V6ONLY on the socket) ipv4 connections are then received and logged as IPv4-mapped IPv6 address.

what's the output of `nc -v ip.of.pbs.server 8007` when run from a client trying to connect to PBS?
do you have any firewall (nft, iptables) enabled on the PBS, or on route to PBS?

I hope this helps!
