Invalid URI: Invalid port specified after changing the BaseAddress registry key

After changing the BaseAddress registry key you might receive an Event ID 100 and 150 Error in the Operations Manager Event log.

After setting the BaseAddress registry key in the Windows registry to a different value (as described here), you might start receiving Event ID 100 and 150 Error in the Operations Manager Event log.

The issue is that if - for example - you add an url like "http://localhost:5003/" you must not forget to add the trailing slash "/". If you do not add the slash, you will receive an "Invalid URI: Invalid port specified." Error in the Operations Manager Event Viewer.
