Cannot post to my Facebook GROUP

Cannot post to my Facebook GROUP

I've been posting to my Facebook Page, Group, Instagram, and Twitter for months.

Suddenly, the GROUP posts no longer successfully post and after every attempt, Zoho tells me it's disconnected. I reconnect. Post. And disconnects instantly after failing to post.

Facebook seems to be linked fine, it's just Zoho's end. Can you tell me what's going on please?
