Port status unknown

Hi, since Tribler 6.5 i have issues to download torrents because 99% of the time it says port status unkown.
I have already posted a topic on that a few month ago but this problem is still unresolved.
I’m on MAC, and i’ve already gone to https://github.com/Tribler/tribler/blob/devel/CONTRIBUTING.md but it changed nothing.
Thank you

If you click on channels and you see a list of the channels than Tribler is working.
I get here the most time no green round but the yellow triangle.

Tip Add a torrent to try. Go to a torrent website download a torrent add this to the map downloads go to Tribler. Click on the top right on the red cross. and add the torrent browse to the torrent file.

keep in mind that Tribler is working a lot slower than a normal bit torrent program, this have to do with the anonymity.
