After fixing some issues with the computers, you should be able to connect.
It seems that your issues have been solved. If you have again this issue, reactivate the local backend and then activate the remote backend to reset the IP configuration.
The problem has already been solved
It seems to work. Thank you!
Since half an hour ago there is a network problem at the URJC Fuenlabrada campus and so the remote backend for Unibotics is not available. Just use the local backend instead.
Eventually that network problem will be solved along today.
