Updated and no way back - no tracker connecting...

[Guillme]

Hi !

I have been using Transmission for years and it was always working properly. today I conducted an update to transmission 4 and since then it is not impossible to connect to tracker-
My router is an o2 home box. I did enable Upnp and now I am back to transmission 3 (on a Os Monterey) but it is not working either. I tried hard different setting on the router - like desactivating UpnP and manually opening a port etc. no success.

I would appreciate some help, thank you.

here is the log:
