Plesk has a similar report, too:
Cause
The issue is related to the latest Apache update, which changed the approach in handling UDS URIs used to proxy connections from Apache to PHP-FPM.
Theirs (which must not mean theirs) solution is to downgrade Apache 2 and put it on hold.
Ubunutu 20.04:
# export version="2.4.41-4ubuntu3"; \ apt-get install apache2=$version apache2-utils="$version" \ apache2-data=$version apache2-bin="$version"; \ apt-mark hold apache2
