AH01079: failed to make connection to backend: httpd-UDS

    Hi guys,

    For some reason one of my Word Press sites has stopped working and I'm seeing this error in my domains log:


    Code
    1. [Mon May 31 12:33:54.008478 2021] [proxy_fcgi:error] [pid 1150:tid 548220600736] [client 192.x.x.x:57536] AH01079: failed to make connection to backend: httpd-UDS
    2. [Mon May 31 12:33:54.676767 2021] [proxy:error] [pid 1150:tid 548212208032] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php5.6-fpm-mydomain.com.sock (mydomain.com) failed

    Any ideas what could be causing this? I'm still using PHP 5.6.


    Thanks,
