RaspberryPi & Deluge Seeding works -Downloads not at all

[Milorad]

Greetings to all,
My downloads are stuck. If I close et restart deluge downloads will resume, but only for a very short moment.

I’ve opened a listening port on my router, except that Deluge will not accepte the designated port in the prefs, using the web GUI or Deluge installed on the Mac. I wish to do it with the terminal. In which file can I specify the port, and where is it located ?

Thank you for your time.
