Cause

The browser cache contains the older version of MTC-M client and new version of MTC-M apache tomcat server.

Resolution

IncompatibleRemoteServiceException means that the browser cache contains the older version of MTC-M client and new version of MTC-M apache tomcat server.

To fix this error:

1. Stop MTC-M STC.
2. Open your browser and close the tab which is accessing the MTC-M client.
3. Clean your browser cache (most important step)
4. Start MTC-M STC.
5. Open MTC-M client tab again and try to login.

Note: Alternatively - for testing purposes you can use incognito mode, or a different browser, that you didn't used to connect to MTC-M before.
