Cause

Under certain circumstances, Veeam ONE Monitor Client cannot establish connection with Veeam ONE Monitor Server.

Solution

These are the most common situations that we recommend checking:

 
1. Make sure Veeam ONE Monitor Server service is up and running.
1. The name of the Veeam ONE Monitor Server is correctly specified in the Veeam ONE Monitor client settings.
2. The Veeam ONE Monitor Server is reachable from the machine where Veeam ONE Monitor Client runs.
3. In multi-Monitor Client environment, connection to Veeam ONE Monitor Server may fail with one of the following errors:
 
Service connection failed Address = \\IP_Address\pipe\VeeaMDCS Error = 0xe7
Service connection failed Address = \\IP_Address\pipe\VeeaMDCS Error = 0x5

To resolve this issue, add the Veeam ONE Monitor Server service account to the Veeam ONE Administrators security group.
 
4. The ports used by Veeam ONE Monitor Client to connect to the Server have to be opened:
TCP/139
TCP/445
UDP/137

Besides these standard ports, Veeam ONE Client also uses dynamic TCP ports 49152 - 65535. Check if the mentioned ports range is open on the firewall.
