Error connecting AFV

Dear all, new here. Downloaded AFV, but when I try to connect to the network I get this error:

Anyone who can help me with this?
Kind regards

Not sure. Don’t remember ever seeing that one.

Which ATC client do you have running? Maybe ask your ATC instructor / mentor staff if they’ve seen that error?

I’m using Euroscope. But for now I want to use it as a pilot.
I adressed it in mijn own VACC as well. Some reactions on it, but it is problably a difficult error.
Is there any AFV Support option?

AfV is only for controllers. If you’re flying, the voice stuff is all handled through the pilot client.

I saw that later.
But I like it to be resolved before I start controlling as well…
