Hi all,

I have the above error and can’t seem to find a solution. With the research I’ve done so far, some suggested this is an account authentication issue. I’ve ensured that this is not the case. I’ve checked to see if the the port 11731 is being used by another process. It’s not. It’s free and listening. I tried recreating the job, no joy. I’ve rebooted the server to nil effect.

Does anyone have any other suggestions?

Thanks in advance.

What version of Veeam are you using?  What OS is it installed on?  Did you check the logs - C:\ProgramData\Veeam\Backup

Also I would search the forums as well https://forums.veeam.com

Worst case create a support ticket.


Hi,

Server 2019, Veeam ver 11.0.1.1261

Logs do not shed any more light on the cause unfortunately, as least as far as I can decipher.

Any reason you have not upgraded to Veeam 12.3?  That version is fairly old and out of support.  You may want to consider upgrading and then check if the issue persists.


Yes, I’ve been considering that as well. I think I’ll do that before further diagnosis. Will update accordingly.


Hi ​@robns,

What exactly is the task that fails? I know port 11731 from an agent deployment scenario so maybe Veeam is trying to deploy an agent to a target system?

In case I suggest right there might be either permission errors on the target site or a local or physical firewall is blocking ports. Maybe you should check the situation on the target as well if there were changes made.

 

I also agree with Chris, you should consider opening a support ticket.

Agree with Lukas. Needing to know what task you were/are doing?

Is this error in a Backup Job? Replication Job? Copy Job? Agent? Or, are you trying to add a Veeam Component or Managed Server? Needing more info on what you’re trying to do ​@robns . Let us know if upgrade resolves your issue.

Best.

Sounds good.  Let us know what happens after updating to 12.3 and the backup status.


Hi Guys,

 

Haven’t update the version yet but I found the issue. It was mentioned here: https://www.veeam.com/kb4495

Note: Use of a local account other than Administrator will likely fail; see KB4185.”

Once I used the server’s local Administrator account (this is a member server, not on a domain) for the physical server in Veeam > Inventory > Physical Infrastructure > Protection Group, it successfully scanned the server and backups now run. I was using an account that was a member of the administrators group. For some reason, this stopped working.


Great to hear you found the solution and thanks for posting it here for others.


Glad you were able to solve your issue. Thanks also for sharing your resolution. 

Best.
