It feels really awkward to see " redis: uncaught exception: Redis server went away " when it was working and suddenly this message bumps up. I faced the same situation while accessing php redis but I guess it's more generic one, more related to redis. So, here are possible solutions that I am able to find and highlighting the one which really did work for me. 1. /usr/sbin/setsebool httpd_can_network_connect=1 By default, SELinux does not allow Apache to make socket connections. So, enable the connection. 2. Try to stop the redis server and restart it again. either of these two should work: a) redis-cli b) redis server 3. There might be issues with switch, try to use different switch.
The blog will contain all the Technical knowledge I have to share and I welcome & would appreciate others for sharing their knowledge :0)
