recently the root CA which signed Let's Encrypt certs expired. Is it possible that this may be the reason some plugins can't connect to the websites using LE?
This website uses Let's Encrypt, it's called from databazeknih plugin (

The same query from Firefox works. Is it possible, that the python3 bundled with Calibre, uses https code with its own CA store which is old, therefore can't verify Let's Encrypt https communication?
I'm running on Windows 10 PRO x64 eng.
