Problem accessing cloud behind a proxy

[Davide DB]

Hi all,

I connected without proxy via my mobile phone.
I set "No proxy" on preference dialog. I saved and restarted
Subsurface several times.
No way to connect to the cloud. The UI is plain wrong because it says
successfull connection but no dives are displayed.

Starting Subsurface with -v I see from the cmd window that it still
using the proxy getting the the infamous "incorrect parameter" error.

Where are those preference saved? How I can delete them?

Thank you in advance
