Windows Agent Backup error

[psych]

Hello,

So the story is that I added new backup job with type of Windows Agent Backup, all other backup jobs working fine. Windows server is not AD domain joined, Windows Server standard 2019 (1809, 64 bit). Eventually, agent was installed from Veeam B&R 11 server and it was reachable and also was able to make a backup to remote repository. Now agent gets warning when I try to rescan host - 1 host processed with warnings. When I try to run backup job - it gives error saying Processing hostname Error: Failed to connect to hostname:6160. I tried to telnet from R&B to Windows machine and I can connect. Not sure where is the problem. I know that server is reachable from R&B server, required ports are opened.
What I tried already:
opened ports on Windows machine following this article https://helpcenter.veeam.com/docs/backu ... ml?ver=110
Restarted server
Edited local security policy by allowing the following: Restrict NTLM: Incoming NTLM traffic

From logs what I found, not sure where to look:

Hi!

Whenever there are technical problems, feel free to open support case to find the root of it.
Side note, your link refers to VBR ports used with managed Windows Servers. For Veeam Agent management related connection ports please check this guide.

/Cheers!

Hi,

Thanks for your reply. I looked at your posted guide and added few more ports but still but still problem is there. I don't see what particular warning it gives me for more clues other than just "warning" when I am re-scanning hosts. Don't see why it can't connect via 6160 while ports are opened.

[psych]

Also to confirm at least 6160 port I tried to run tnc from both sides, seems OK to me.
This is what I get:
From R&B to Windows server:

Code: Select all

PS C:\Users\Administrator> tnc  -port 6160 -informationlevel Detailed

And vice versa:

PS C:\Users\User> tnc  -port 11731 -informationlevel Detailed

NetRoute (NextHop)      : 192.168.1.254
TcpTestSucceeded        : True

So I am wondering where is the problem if not in the port?

Hi Psych,

Our customer support engineers will be happy to troubleshoot that for you. Without logs and environment analysis which is done on the customer support end, it's hard to say what's going on there.

Thanks

Hi,

Thanks for the reply.
I have trial actually and thus I cannot open a case in the support center. How can I get a technical support for a trial?

[wishr]

We do provide customer support via common channels for customers using free products. It is provided on the best effort basis.

Please, note, that you should specify a case ID when posting about any technical issue on these forums (as mentioned when you click New Topic and Post Reply), otherwise the post may get deleted.

I hope that helps! Thanks.
