I have the following configuration in my router:
Code:
DNS servers used
8.8.8.8
8.8.4.4
2003:180:2:9000::53 (currently used for standard queries)
2003:180:2:7000::53
This configuration is used from both my Windows and my Apple Mini (and all the other devices on the network). Calibre on the Apple works, so I don't think this is the problem.
Nevertheless, I changed my DNS configuration manually on my Windows computer as well to give it a try:
Code:
IPv4 DNS servers: 8.8.8.8 (Encrypted preferred)
8.8.4.4 (Encrypted preferred)
Also checked with ipconfig /ALL and retried with Calibre on Windows - same issue.
Somehow I have the gut feeling this is related to the way the Python programs are called (http\client.py). How does this work and is this something I can verify? The first call that usually fails is "mechanize\_urllib2_fork.py". Maybe there is something in Windows 11 which blocks this communication.
Otherwise, there is not much left. It worked before on Windows, it still works on my Apple Mini, and I did not change anything in my network configuration. If I manually enter the URLs (e.g.
https://www.google.com/search?q=3809...Awww.amazon.de into a browser, they are working fine. I think something is blocking the internal Python URL calls (even in Windows Safe Mode), so I think it must be OS related.
Any clues where to look?
What really puzzles me is that this worked perfectly fine for many years on my Windows computer as well, with the same configuration, same AV program, same network settings, same router configuration, ... and it still works in the same network with my Apple Mini. And I have not changed anything- except I updated to Windows 11. I can't even blame Kaspersky, because I have the same issues in safe mode.
Anyway, thanks for all the suggestions. Any further ideas I more than welcome

Claus
