Hello everyone, I have upgraded Proxmox and it seems like the Proxmox Backup Server is blocking my connections. The PBS has a public IP, and when I connect from there, it works perfectly. I can't understand what might be blocking my connections. The other machines are connected perfectly, and I can't figure out what's happening

Can you web browse to 10.10.10.1:8007?

Is that definitely the right IP address? Usually 10.10.10.1 would be your router.
 
Hi, it's about a private network that I used to make the machines communicate with each other, but they are also connected to a public network. The private IP 10.10.10.1 is already used by other nodes. The problem occurs only with one node when I try to reconnect it.
 
"Connectivity is there, it responds to the ping without issues, but it gives this error as if there is a block by the server on the private interface, because it works on the public one."
 
Ping aint enough, hence I proposed checking the port with telnet: check that you can actually reach 10.10.10.1 port 8007 from that PVE host. There could be a firewall allowing ping but not port 8007/tcp.
 
There is no firewall on that port, telnet works, and it is correctly detected when performing a port scan with nmap. Also, I configured the machines myself, and because two other nodes that perform backups work perfectly. I only have problems with that client which doesn't work
 
One more verification: curl -Ik https://10.10.10.1:8007/api2/json/nodes/localhost should return something like:

HTTP/1.1 401 Unauthorized

In PBS server:

- Is there something relevant in logs /var/log/proxmox-backup/api ? Do you requests show there?
- Check journal for something relevant: journalctl -f -u proxmox-backup-proxy.service and journalctl -f -u proxmox-backup.service.
