Boldgrid connection error

BoldGrid Connection Issue
There was an issue reaching the BoldGrid Connect server. Some BoldGrid features may be temporarily unavailable. Please try again in a moment.

If the issue persists, then please feel free to check our BoldGrid Status page.

I have been recieving this error for the last few days. I’ve tried renaming the  plugins file as suggested somewhere else but nothing has worked so far. When I access my cpanel file manager there is an error log that says :

[27-Jan-2018 18:05:07 UTC] Boldgrid_Inspirations_Update::update_api_data: Failed to get valid updated boldgrid_api_data.  Array

Please help!
