VSPC failing to connect to Cloud Connect – “Failed to connect to the deployment service”

I’m unable to connect VSPC to Cloud Connect. When I try to add the Cloud Connect server from Configuration → Catalog → Veeam Cloud Connect, it fails with “Failed to connect to the deployment service.” I’ve already tried disabling Windows Firewall and antivirus, but the issue persists. I can install the agent manually on the Cloud Connect server without any errors; however, after installation, the server only appears under Discovery in VSPC and does not show up under Catalog → Cloud Connect → Veeam Cloud Connect Integration. Both servers are on the same subnet with no firewall in between.

      Be sure the credentials you are using are local Administrator access.  If you install the agent manual you can move it to VCC using this registry key -

      • Solution: Connect to the Veeam Cloud Connect server machine, stop the Veeam Management Agent Service service, and open the Windows Registry Editor. Navigate to HKLM\SOFTWARE\Veeam\VAC\Agent and change the AgentMode DWORD value to 3. Restart the Veeam Management Agent Service. The server should then appear under Configuration > Cloud Connect Servers in VSPC.

        ​@chamandeep  We had similars issue during the VCSP 9 upgrade and it was fixed by 

        1. Stop the Veeam Management Agent Service. 
        2. Edit the json file "C:\ProgramData\Veeam\Veeam Availability Console\Configuration\Agent\configuration.overrides.json" 
        3. Find the “Agent_AgentMode” entry and change it to 3 
        4. Start the Veeam Management Agent service
