Hm, I can’t find any error reports for this device model. Also no other users have reported issues.
Your SeriesGuide is not connected to Cloud, only to Trakt? Did you try on another connection? On your device you probably can access https://www.themoviedb.org and https://trakt.tv?
@Daz Is SeriesGuide Cloud connected? That will turn off Trakt syncing. Otherwise, try to disconnect and connect Trakt again? Also maybe check Help | SeriesGuide
