Hello there,
I'm writing here because I'm facing huge problems with GOG Galaxy. I have troubles logging in, syncinc my savegames etc...The app gives me the "Sorry, we couldn't load the data" message.
I tried reinstalling the application as well, but the installer couldn't download the setup ("Cannot connect to GOG.com. Check your internet connection"), so I had to download an offline installer but it can't log-in anyway.

Am I the only one facing this issue? How can I try to fix this?

TEMPORARY SOLUTION (as the problem will happen again):
As someone else said elsewhere, looks like solution exists. Open CMD as administrator and type in "netsh winsock reset catalog", then restart the computer.

Well the problem is back on and this time the CMD command is not working.

I would really like to update Cyberpunk 2077, but this issue is not allowing me to do anything.
