After launching the Veeam ONE Client, a pop-up appears with the message: Could not connect to Veeam ONE Monitoring Server specified in Settings > Client Settings.
This occurs when the Veeam ONE Client cannot connect to the Veeam ONE Monitoring Server specified during the launch of the client. Specifically, this could occur because: The server specified is not a Veeam ONE Monitoring Server. The Veeam ONE Monitoring Service is not running on the specified server. A firewall is preventing communication between the server where the Veeam ONE Client is running and the specified Veeam ONE Monitoring Server.
Verify Server and Service Launch the Veeam ONE Client and double-check that the server specified is, in fact, the Veeam ONE Monitoring Server. Note: If the server was specified using its hostname or FQDN, ensure that the server where the Veeam ONE Client is running can resolve said hostname or FQDN.
If none of the troubleshooting steps above resolve the Veeam ONE Client connection issue, please create a Veeam Support Case.
