Unfortunately nothing changed. Same error.

it's unlikely to help but it's possible to direct kodi to the cacerts with advancedsettings
https://kodi.wiki/view/Advancedsettings....k_settings
 

Code:

<network>
<catrustfile>filepath</catrustfile>        <!-- Added in v19- Allows specifying a custom SSL CA trust store bundle. e.g. special://masterprofile/cacerts.pem -->
</network>

barring that then i guess it would need "|verifypeer=false" appended to the url but that has to be done in the addon code

Uninstalled TheMovieDB Helper. I don't know what I needed it for but it didn't complain about being needed by the skin I currently use. As such, I removed it and I hope to have eliminated the problem at its root.
