v17 - TVDB scraper failing login to thetvdb API suddenly

All of a sudden in the last two days (with no changes to Kodi or the scraper), the TVDB scraper stopped working.

This is Kodi v17.6 running on Linux (Opensuse Leap). TVDB scraper 3.0.1

Looking at the logs, it seems the initial call to login to pass the API Key for kodi to get the token for further calls is failing with SSL error 35.

The curl to the API from command line on the same machine works fine and gets the token

Any idea what may have changed underneath?
