I’ve installed Veeam with a 30 day evaluation license. It works fine for VMs. However, when I try to back up the physical host using a Windows Agent, I get the error:
Managed session has failed: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.1YY.1.XX:10005
The endpoint running the agent can ping the backup server, and the backup server can ping the endpoint. They are all domain joined devices. There is no firewall between the endpoint and the server other than Windows Defencer with Advanced Security and all of the necessary Veeam in and out rules are present. However, the following command fails with message TcpTestSucceeded = False:
Test-NetConnection -ComputerName backupServer.mynetwork.local -Port 10005 -InformationLevel Detailed
The backup server port 10005 is listening and not blocked by another application. The backup server has been rebooted several times, and that makes no difference. I have also installed the agent on a number of other physical devices, and they all have the same error/fault.
I suspect the problem may have something to do with the NIC configuration on the backup server. It has 2x NICs. The LAN NIC is 192.1YY.1.XX/24 and there is no default gateway. There is a WAN NIC which is 172.16.A.BB/24 with default gateway 172.16.A.1. There is a DNS server on the LAN NIC but no DNS on the WAN NIC. (In effect, the backup server is in the DMZ and connects to our Azure instance and storage blobs.)
Is there either an agent configuration file (.xml or other) that I can look into to see how the agent is configured, or registry keys to check? Is there any Veeam guidance documentation about installing Veeam backup and replication server on a multi-NIC host? Has anyone got any suggestions? Thank you.
