From Nginx Error Log:

2020/03/27 23:06:41 [crit] 17190#17190: *8 connect() to unix:/var/run/php7.2-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 98.247.186.101, server: _, request: "GET /mail/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7.2-fpm.sock:", host: "mail.longlookconsulting.com", referrer: "https://mail.longlookconsulting.com/"

When I try to access my Roundcube webmail site I get a 502 - Bad Gateway error. In my Nginx logs I am seeing the error above which appears to be looking for my sock file in unix:/var/run/php7.2-fpm.sock, but there is another nested folder that should be reflected in there (unix:/var/run/php/php7.2-fpm.sock). I have been messing with this all morning and I just cannot find what configuration file is being used to direct to that address above.

My /etc/php.7.2/fpm/pool.d/www.conf file has the following listen line which I thought would be used:

listen = /run/php/php7.2-fpm.sock

But it's clearly not doing the driving here, so I'm lost as to where this needs to be changed, and where I presume it was broken when I updated my server to Ubuntu 18.04.
