Subtitles addon error

Hopefully someone around here can help me, as I suddently have problems downloading subtitles.
Just to be clear, it worked perfectly yesterday – but I did a fresh install and restored my backup on my fresh install. (Long story short, my partition was too small for LibreELEC so I had to do a new and fresh install to update to the latest version)

I downloaded the latest version of LibreELEC, and did a backup of my old install. Then I restored my backup to the fresh install, and everything works as it should – but not downloading subtitles from Subscene and OpenSubtitles. This is the error I get from the addons;

Code:

I’ve tried to delete the addons, delete the addon data in the userdata directory and installed them again. However, no luck at all. As I said, this worked perfectly before I reinstalled LibreELEC. Anyone have any ideas what causing this?

I appreciate any help I can get to solve this.. Maybe I just have to do a clean install and don’t restore any old backups? I hate to loose my watched status, settings etc 🙂

Thank you!
