Hello & thanks for the quick response.
Let me start by saying that my level of technical skills is extremely low... so low that it took me 15 minutes (conservative estimate) to figure out how to save the error log...
I am an an old school social scientist who happens to love search problems, so please be patient;)
As far as I know, no proxy is involved. I thought my vpn could be in the way (Mullvad) but turning it off does not change anything (and it usually does not interfere with activity on the local network).
This being said, I've tried 3 browsers, with/without addons and none worked, so the problem is likely to be at the network level... or not
Since it appears I cannot upload a text file, I'll copy the content of the log file below.
Again, thanks for your help and sorry about my ignorance
Argh, now I'm being told I've exceeded the number of characters... so I'll try to paste the logs in another post...
