When issue was visible I saw that fbc page was loading and after short period of time it's getting covered by some kind of blockpage.
Like message about locked account is in the foreground and a normal fbc webpage is in the background. I tried to blocked it by adding filter to "ublock" plugin but without success.
Then a tried to check network logs from developer tools built-in browser.
I also saw this suspicious url bitwrecked.
 
Unfortunately I didn't took any usefull screenshots or save any logs.
I know that now it's impossible to proof anything.

At some point when I had these two scripts blocked it started to work

But now even with allowed these two scripts to run, page is loading successfully without any concerns.
It looks and works as usual.
