Hi,

Thanks for your quick reply.

The issue seems to have been solved by itself... Nothing changed on my side (I kept connecting using my wi-fi network). My ports rules policies were already fine. I still cannot figure out what happened exactly (as I didn't see any change with my ISP connection & local network).

Well, let's consider this issue as solved (since it was the first time I had it in 3 months). I will notify you whenever the problem becomes recurrent !
