Plug-in is no longer working with my Facebook groups

Hello,
I need your help. I run Wired868 and I link my site to two Facebook groups:
https://www.facebook.com/groups/Wired868/
https://www.facebook.com/groups/wired868volley/
I had to manually import comments from both for months. Suddenly, a few minutes ago, both groups disappeared from the plug-in and I don’t even have the option to import them mself.
Can you help me link them back to the site?
Thank you.

Best regards,
Lasana
