No Internet Connection Try Again - Facebook login message

Hello,

• I suddenly lost access to all Facebook posts’ contents (I would see a grey space) and access to my private Facebook groups. Following steps found in google searches:
• I shut down all my apple devices (several times - after each time I implemented a suggested step )
• I checked: there is no problem with my server for both cellular and wifi connections. Everything else works perfectly and quickly.
• I deleted/uninstalled Facebook apps on all my devices. I reinstalled the app again. Now, as I try to login, I get the ‘No Internet Connection message Please check your connection and try again’ message. Incidentally, I don’t see my photo above my name when I try to login. It might be customary, but as I haven’t done a logout and login on FB for a while, I can’t remember.
• I toggled Facebook and App Store in my devices’ settings wherever I could see them (cellular data, background app refresh, automatic downloads, app updates, etc. whatever was suggested in my searches and what could be toggled!)
• I deleted my internet browsing history [sigh] from my iphone’s settings

I still get the No Internet Connection message when I try to login to Facebook.

Any suggestions? Thanks …
