[foosion]

I'm getting SSL certificate problems. All was working well until this morning. I can still check out books through my library, download the acsm file from libbyapp.com, import into ADE and import into Calibre.

The error is in the overdrive libby plugin, but the issue seems to be here.

I tried importing the certificate mentioned in #450 in this thread. However, https://acs.cdn.overdrive.com mentioned in #449 gets a 404 not found error.

The certs I imported were 1p5.crt and lets-encrypt-r3.der. Upgrading to Calibre 7.17 didn't help.

Spoiler:
