On initialisation, the blue Stuga screen is trying to connect and the tries number keeps counting up.
Generally, this indicates a problem with the route between the front end and back end PC
If connected network on either front and back end PCs is not "Work" or "Private", this can block communication
If the back-end PC is not on a fixed IP address, and the route is set to connect to a specific IP address, then any change will lose the route connection
Then set up the route again from the front end PC
Log in to back end PC and clear all AMS routes out. This cleans out the system and then you can attempt to create the route again
