Cause

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

Solution

To resolve the problem, make sure that:

  1. The name of the machine where Veeam ONE Monitor Server runs is correctly specified in Veeam ONE Monitor client settings.

  2. Veeam ONE Monitor Server is reachable via network from the machine where Veeam ONE Monitor Client runs.

  3. The user account which is used to run Veeam ONE Monitor Client is included in the Veeam ONE Users security group (at least) on the machine where the Veeam ONE Server component is installed.

  4. As per Veeam ONE v6 Release Notes, 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.

  5. The ports used by Veeam ONE Monitor Client to connect to the Server are getting blocked by firewall. Make sure these ports are open on the firewall:
TCP/139
TCP/445
UDP/137


Besides these standard ports Veeam ONE Client is also using Dynamic ports in the range from TCP/49152 - 65535. Check if the mentioned ports range is open on the firewall.
