[possible bug] HTTP 503 error due to directadmin not aligning socket files

[mik3ca]

Currently any request to a PHP file on my server regardless of domain returns HTTP 503 error. my system is setup to use apache to connect to PHP through php-fpm (the default shipped with directadmin)

The template file for directadmin for php-fpm is this:

/usr/local/directadmin/data/templates/php-fpm.conf

and its contents are:

|?PHP_VER=54|
|?OPEN_BASEDIR_PATH=`HOME`/:/tmp/:/var/tmp/:/opt/alt/php`PHP1_RELEASE`/usr/share/pear/:/dev/urandom:/usr/local/php`PHP_VER`/lib/:`ACTIVE_USR_LOCAL_PHP_LIB`:/usr/local/lib/php/|
|?EMAIL=`USER`@`DOMAIN`|
|?MAX_CHILDREN=`MAX_CHILDREN_DEFAULT`|
|?MAX_REQUESTS=500|

|CUSTOM1|

[|USER|]
user = $pool
group = $pool

listen = /usr/local/php|PHP_VER|/sockets/$pool.sock
listen.owner = $pool
listen.group = |SERVER_GROUP|
listen.mode = 660

pm = ondemand
pm.max_children = |MAX_CHILDREN|
pm.process_idle_timeout = 20
pm.max_requests = |MAX_REQUESTS|

security.limit_extensions = .php .inc .phtml

php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f |EMAIL|

|*if PHP_SESSION_SAVE_PATH!=""|
php_value[session.save_path] = |PHP_SESSION_SAVE_PATH|
|*endif|

|*if OPEN_BASEDIR="ON"|
php_admin_value[open_basedir] = |OPEN_BASEDIR_PATH|
|*endif|
|*if PHP_MAIL_LOG_ENABLED="1"|
php_admin_value[mail.log] = |PHP_MAIL_LOG_DIR|/php-mail.log
|*endif|

|FPM_PHP_SETTINGS|

|CUSTOM2|

And for HTTP to connect to PHP-FPM, its template file is:

/usr/local/directadmin/data/templates/user_virtual_host.conf

and the contents are:

|*if PHP="OFF"|
|?HAVE_PHP1_FPM=0|
|*endif|

|*if PHP1_RELEASE!="0"|
|?OBDP1=:/usr/local/php`PHP1_RELEASE`/lib/php/|

|?PHP_EMAIL=`USER`@`DEFAULT_DOMAIN`|
|?FASTCGI_SENDMAIL_FROM=-d sendmail_from="`PHP_EMAIL`"|

When DirectAdmin generated the scripts and PHP 8.2 is selected, the line in HTTPD configuration is this:

AddHandler "proxy:unix:/run/php-fpm/php82-1004.sock|fcgi://localhost" .inc .php .phtml

And generated php-fpm config for the user is:

listen = /usr/local/php82/sockets/$pool.sock

I tried changing directadmin from the current channel to the stable channel and I had no luck.

Have I spotted a bug that the directadmin devs don't know about?

and why would the value of PHP_FPM_SOCKET_PATH contain 1004 and point to path where the live sockets are not present?
