Jessie -> Stretch system

Hi,

I've got a system that was originally on jessie.
Attempting to run PHP7 FPM processes render 503 errors .
Errorlog for the sites show:
[Fri Nov 22 01:20:50.001978 2019] [proxy:error] [pid 12486] (13)Permission denied: AH02454: FCGI: attempt to connect to Unix domain socket /var/lib/php5-fpm/web5.sock (*) failed

If I uncheck the Use Socket for PHP-fpm the PHP exeuction works for FPM.
Any idea what might be wrong?

I went through a perfect setup guide for stretch to check so Im not missing any dependency or a2mod .
root@XXX:/var/lib/php5-fpm# ls -la

srw-rw---- 1 web5 www-data 0 Nov 22 01:15 web5.sock


Tried creating a fresh site on this server, same thing.
Not sure what this server might be missing or have issues with. Any idea?

 

I've run php -q update.php and let it reconfigure services.
System ->Server config -> Web -> PHP settings are untouched.
/etc/php5/apache2/php.ini
/etc/php5/cgi/php.ini
php5-fpm
/etc/php5/fpm/php.ini
/etc/php5/fpm/pool.d
9010
/var/lib/php5-fpm
[website_path]/web:[website_path]/private:[website_path]/tmp:/var/www/[website_domain]/web:/srv/www/[website_domain]/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom

Should these be changed?
I'm using additional settings for PHP according to https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/ to add support for PHP 7.2 / 7.3 .

 

Alright, I found an old thread where you mentioned that it didnt matter if it used /var/lib/php5-fpm still.
But can you assist me in what paths are accurate?

I've got PHP 7.0 , 7.2 and 7.3 installed now using the other guide.
So which values for the system global should I set?
