Dear folks,

I have a strnage problem, and I think that there must be an easy answer. But I can't find it through googling. Many thanks for help:

1. Windows 10, latest updates. Windows defender, all Antivirus turned off.
2. I can connect to the Internet via WifI with my browser firefox. Also, thunderbird works fine.
3. However: All programs that work through standard windows options cannot cannot: Chrome, Edge, Dropbox. No connection.

-> It must be sth with the windows settings.

4. What could this be? No proxies.

Unfortunately I cannot trace the problem to any new installation etc..

Thanks for your help..
