I can't connect to Redis

[Joey_M]

Prior to the release of 4.1.19, and the maintenance task which that resolved, I experienced an issue where Redis failed.

It just seems to always fail, and whereas previous versions wouldn't allow the configuration to proceed if it wasn't correct. Now I can type anything and I can proceed to downloading a new constraints file.

I have spoken to a friend who helps me with my server, he suggested trying "/home/domain/.redis/redis.sock" (domain is my site's root folder - I changed that). Along with the IP address which previously worked.

http://127.0.0.1/

Port: 6379

I don't see why all of a sudden it's failing to connect or work.

What is the content of your constants php file?
