Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the webserver log.
You want to access Redis using a socket, although you provided process details which are shownig it is listening on 127.0.0.1 (network). Make sure that the redis configuration (/etc/redis/redis.cong?!) contains the following lines and that the socket is accessible by the web server user (This is ususally be done by adding the web server user to the redis group):
Have you checked if the required php modules are correctly loaded?
For the php cli component, please execute “php -m”
For the php web component, please create a php file, e.g. “info.php”, which contains the line “<?php phpinfo() ?>”. Once you’ve created that file, open it using a web browser and check if a redis module is loaded. (Keep in mind to delete the info.php file after your tests for security reasons )
