PHP File uploading stopped working after an upgrade from 15.3 to 15.4

Hi,

I have a development system that started off as a 15.2 system and was successfully upgraded to 15.3. The system is a Web Server using apache 2.4 php7.4 and php-fpm. Everything worked after that upgrade, but now after the upgrade to 15.4 the php apps will not take file uploads. I tried raw php and my Laravel apps, I get the same results.

I suspected AppArmor, but I have tried everything and nothing works. It seems like the files are not making it to the system. Is there something common that I could be overlooking?

It seems I did everything right, but these lines added to my php-fpm pool config (/etc/php7/fpm/php-fpm.d/www.conf
) helped:

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp
