thanks all for your answers.
However, have been flying sims since the first MsFs.
Perhaps I was unclear. I will post a screenshot when it happens again. Its kinda random. But its exactly like I wrote: only GPS straigt line between 2 airports. No VOR to VOR route or IFR routes can be choosen. Even starting from Amsterdam Schiphol (pretty sure they have a tower, infact they have 2), there’s only a Schiphol Traffic or Amsterdam Center option to contact.
I noticed that, when I proceed to fly anyway, usually after a few minutes the “Azure speech” error message pops up. Perhaps still a server issue and with this also no navigation available? I think that is not server availability dependent but who knows.
I hope its just a temporary glitch.
Edit: screenshots:
