"failed to load license from backup services""

If you are looking for Support you need to open a ticket as the community is not technical support.  Based on what you have done things should work but double check the firewalls between things to ensure ports are open.  Then contact support and open a ticket to attach the logs.

Hi ​@usoyfx -

Have you tried to run netstat -na | find “9392” (or “9396”) to make sure it’s listening on that Port.

You can also run a PoSH cmd: Test-Connection -Port <number> to see if the computer is listening.

As Chris shared, if you’re running the Win f/w, make sure the ports are open on the device.

Also, look at the Veeam KB on A/V exclusions and make sure those are set:

hi ​@usoyfx 

DId you do any changes in your environment? Has it ever worked??

Could you please see the information bellow.

To resolve the "failed to load license from backup services" error in Veeam, verify that the Veeam Backup & Replication Service is running, check your DNS settings, ensure root CA certificates are installed and the VeeamDeploymentDll.dll file is not locked, confirm the correct license file version is being used, and update your license through My Veeam or Veeam Backup Enterprise Manager. 

1. Check the Veeam Backup & Replication Service:

• Open Services (search for services.msc).
• Locate the Veeam Backup Service and ensure it is started. 
• If the service is stopped, try to start it. If it fails to start, check the SQL server connection settings and the registry for correct SQL instance names. 

2. Verify DNS and Hostname Resolution: 

• Ensure your DNS records are correct and that the VBR server can be reached by its FQDN.
• If you suspect DNS issues, you can add the VBR server to your hosts file to temporarily bypass DNS, according to Veeam Community.

3. Check Certificates and Deployment DLL: 

• On the remote Windows machine, verify that the root CA certificates needed to verify VeeamDeploymentDll.dll are present.
• Check that access to the folder where VeeamDeploymentDll.dll is uploaded is not limited and that it isn't locked by antivirus software, as noted in this KB article from https://www.veeam.com/kb4677 

4. Update or Reinstall the License File:

• If the error indicates a version mismatch, you may need to install a new license file for your version of Veeam Backup & Replication, as described in this Veeam KB article. 
• You can also try generating and installing a new license via the Veeam License Update Server. 

Best,
