Upnp fails on amule

Dear forum users, for me the app is giving me errors on the UPNP side while on qbittorrent is working as expected. So… here I am to see if there are any user that had my problem and has fixed it in anyway!
bug:UPNP fails with some routers · Issue #349 · amule-project/amule · GitHub here is the link to the bug upstream. May be I’m failing on some silly thing!
