Website is not accessible, when domain name contains uppercase letters: Service Temporarily Unavailable

Applicable to:

  • Plesk 12.5 for Linux
  • Plesk Onyx for Linux

Symptoms

  • Website inaccessible with the following error:

    Service Temporarily Unavailable

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

    [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
    [Sat Apr 02 14:31:17.150317 2016] [proxy_fcgi:error] [pid 11255] [client 203.0.113.2:48484] AH01079: failed to make connection to backend: httpd-UDS, referer: https://example2.com/profiles/ticket/XJ-447-329/conversation

Cause

This is Plesk bug with ID #PPPM-4284 and Apache ( 57968 ) issue; the fix is considered to be included in one of the next Plesk updates.

Resoluion

The following workarounds are available. Please choose one of them to apply:

1. Change PHP handler to FastCGI.

2. Recreate/rename the subscription with lowercase letters. The renaming can be done at Subscriptions > Example.com > Domains & Websites > Hosting Settings. Since direct renaming will throw a 'domain name is already exists' error, please use the following scheme: Example.com - Example2.com - example.com.
