Who is the fool in this case, me or Mikrotik?

Question

Mikrotik

2 cars. in one network segment. Clean config.
Raised only GRE.
And it doesn't take off.
Is he making a fool out of me? Or Mikrotik went downhill and this screen is a reason to write to the Bugreport?

Thanks

Answer 1

It was the VERSION. GRE rises only to 6.46.8! And it won't start on any other.
THANKS TO ALL.

Answer 2

I have 10 tunnels closed on the last stable one. There are schemes with a smaller number of tunnels on jumping versions, but all of the XX.y format where xx are the same.
