DM added to DASH will not work

I re-added DM to my DASHBOARD, using the following as a guide.

However, when I try to navigate to the DM via the DASHBOARD, I get the following error...  I have provided system details further below.

  • The NullPointerException is, unfortunately, very generic and doesn't help pinpoint what the underlying problem might be. However, I do know of one problem that seems to be common. 

    On the machine where SQLDM is installed, can you open Registry Editor and go to HKLM\SOFTWARE\Idera\SQLdm. There should be subkey named Version. If the value for that subkey is, change it to (basically delete the last character) then restart the SQLDM Rest Service. Once restarted, try to access the SQLDM web console again.

    If the Version subkey is already set as or you are running a version different from 10.4.0, then I think contacting support would be your next best step.
