    The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

  • A website on Magento is inaccessible with the error:

    CONFIG_TEXT: ERR_TOO_MANY_REDIRECTS

  • Website name contains upper-case letters and it is using Apache + PHP-FPM.

  • The following error can be found in /var/www/vhosts/example.com/logs/error_log:

    CONFIG_TEXT: [proxy:error] [pid 11255] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /home/httpd/vhosts/system/example.com/php-fpm.sock (*) failed

Cause

Product issue:

  • #PPPM-4284 "Support issue PPPM-4284"
    Fixed in:

Resolution

Please consider updating your server:

Workaround

If update is not possible for some reason you may try the following

workaround

Upgrade to Plesk Obsidian Release Candidate 1.0 which is currently available for early adopters.

If upgrade is not possible, as a workaround do the following:

  1. Log into Plesk UI.
  2. Go to Plesk > Domains > example.com > PHP Settings and change PHP handler to PHP FastCGI or PHP FPM served by nginx.

    or

    Recreate or rename the subscription using lowercase letters only. The renaming can be done at Subscriptions > example.com > Domains > Hosting Settings. Since direct renaming will throw the "domain name already exists" error, use the following scheme: example.com - example2.com - example.com.
