HI, we are using veeam to backup out proxmox cluster. Sometimes, on random VMs we are having this error: "Failed to connect the NBD server to the hypervisor host". On the veeam logs i found this "{ "arguments": { "addr": { "type": "inet", "data": { "host": "localhost", "port": "63884", "keep-alive": true } } }, "execute": "nbd-server-start"}"2025-09-15 15:40:01.3401 00040 [1580] INFO | [SshQmpSocket]: Text received from QMP device:"{"error": {"class": "GenericError", "desc": "Failed to find an available port: Address already in use"}}". I opened a case with veeam aswell, and they are looking into this. They suggested i speak to you aswell. Thanks.
