Through my phone I can connect, through my computer I can’t.
The fact that I can connect to my home WLAN (Internet-Box-2) from abroad using the “data roaming” feature of my phone either using (a) directly my phone (on Android 11) or using (b) my new tablet (on Android 10) or © my old tablet (on Android 6) by tethering through Bluetooth with my phone, shows that the connection parameters are duly set and that my Internet-Box 2 seems to respond correctly.
My problem arises if I try to achieve the same connections having my devices connected to another local WLAN (clearly not my home WLAN). Practically, if I cut my working data roaming connection and I switch back to my local internet connection, the connection to the home WLAN fails and I get back a cryptic message saying that _“The connection was prevented because of a policy configured on mine RAS/VPN server. Specifically, the authentication method used by the server to verify my username and password may not match the authentication method configured in your connection profile. … blabla…”.

Please consider that I did install an additional Internet Booster that should enhance the Internet signal through a G3/G4 phone connection (?), due to a very bad Internet connection where my home WLAN is located.
Why on earth I can’t connect remotely to my home WLAN going through my local (abroad) Internet connection?
Who can give me a hint on what I should check further?
