Problem

Problems with the connection between the UMS console and the UMS server may be caused by a difference in software versions, e.g. if the UMS server was updated but the console still uses an old version.

Solution

Check the version status:

1. Check the version of the console by selecting Help > Info from the UMS console menu.
2. Check the version of the server by selecting Help > Info from the UMS administrator menu.
3. If necessary, update the UMS console to the same version as the server or newer.
