This happens in the last few months, literally, 1-2 times during every training season... I click on "start training" button and the connection error starts instead... I've sent the ticket to support and they, as usual, blame me, instead of investigating the issue... No, Nordeus, clearing cache didn't solve the problem (that's always their answer, btw, whatever the bug is)...
