you asked for:
250.0-24.199.212.125.in-addr.arpa 
but got:
255.0.199.212.in-addr.arpa

that's different therefore the mismatch.


Why do you query for 250.0-24.199.212.125.in-addr.arpa by the way?

I got the same results for both queries, but UDP is allowed while TCP is
refused.
- no matter if I ask for any or for ptr.

seems that default for 'any' is TCP, while for 'ptr' the default is UDP.

TCP is required for working DNS - they should not block it.


again, why you query for 250.0-24.199.212.125.in-addr.arpa ?

under normal circumstances there's no point of querying that name.


there
