Hi guys,

I've been trying to download news from Libération for quite some time but I always get the same error:

During handling of the above exception, another exception occurred:

I'm using Calibre 5.30 64bit on Windows 10. I've tried this on previous versions of Calibre and the same error occurred. I've checked this forum for similar problems and I've found this possible solution: https://www.mobileread.com/forums/sh...postcount=1139

However, I don't have the Intermediate R3 certificate on my system, so the solution is not viable for me. Just to be sure, I've deleted also the DST Root CA X3 and tried again, but the same error occurred.

Thank you for any ideas on how to solve this.
