Unable to sync - internet issue

[olivia-hc]

The first sync seemed to work fine. I sorted one conflict I had and then deleted the fit folder. After this I started getting an "unable to sync error" (I've attached the screenshot for the full message, but it essentially relates it to the internet). I disconnected & then reconnected to my WiFi source and still got this issue. I then tried uninstalling & reinstalling this plugin (I'm thinking maybe this wasn't a good idea but alas) in case it was the fit folder deletion that was the issue and that didn't work either.

Any suggestions?

(thank you by the way though)
