It seems we have people having different issues here
## Run tests locally and submit buttons are disabled.
This is basically caused by two reasons:
1) Deadline is passed
2) Not detected as active exercise
What you can try is to in 'file manager / file browser' rename/move exercise project, let tmc redownload it and then copy the old folder back replacing the one downloaded by tmc.
Path where files are downloaded can be seen in TMC -> Settings. Probably NetBeansProjects/CourseName in your home directory.
I can confirm that it is online -> I would suspect to have local connection issues. Maybe your firewall or isp is blocking (not likely in europe though).
Try accessing that url with your browser, does it work? if yes then its most likely your firewall.
Let me know your IP address (
http://ip.jamo.fi) in separate email so that I can confirm with our servers whether we are receiving any traffic from that ip.
Most likely if using windows it is your antivirus or firewall or both.
