It was in the error log

I have IPB 4.7.1 and PHP 8.1.9

Unless it’s continually happening for long periods of time, it’s fine. It’s saying you made a request to Facebook, but it timed out with no response after 10 seconds. 

If it happens infrequently, it’s most likely just a temporary routing issue between your server and Facebook. If it’s ALWAYS happening, a firewall or something similar is blocking your server from reaching the Facebook endpoint. 

As Randy mentioned, this is an issue with your server reaching Facebook. If it happens temporarily, it probably is an issue on Facebook’s side but if it continues consistently, it may be on your end and you need to contact your hosting provider.
