Please see the relevant FAQ entry: FAQ - LazyLibrarian Documentation
Not sure exactly when it started (was sometime in the last 2-3 weeks), the Goodreads sync in the LazyLibrarian container broke. The error is below, which seems to track with the fact that Goodreads still uses TLS 1.0 per the FAQ. It was definitely working a month ago, so maybe an update to the packages within the container removed support for TLS 1.0. Any chance this can be reverted as Goodreads Sync is a major part of the LazyLibrarian workflow?
