This error is apparently due to an expired root certificate from Let’s Encrypt that might be stored in your Windows.
Calibre uses the Mechanize library to create a browser object and downloads pages using that. That object uses the root certificates from Windows and so is affected by the expired root certificate. The browsers have their own certificate store and so they are unaffected.
To delete the expired certificate:
Open the Certificates Manager by starting certmgr.msc. This shows the certificates in the stores on your Windows.
In the left pane, choose Intermediate Certification Authorities -> Certificates.
In the right pane, choose the R3 certificate from Let’s Encrypt. Make sure that its Expiration Date is in the past. If so, delete it.
Close the Certificates Manager.
After this, Calibre should be able to download the news.
