AWS ElastiCache – Not Connected

Tired everything I could, short of re-writing the plug-in to get this to connect to an ElastiCache instance of Redis.

I’ve verified the PECL Redis is available under PHP-FPM and can telnet successfully into the the Redis on ElastiCache. I’ve also tested it with a simple PHP CLI script that connects and sends a PING and receives a PONG from the server.

Installed a REDIS server on the same machine as localhost, changed my settings and it connected fine… just does not want to talk to ElastiCache.

This plugin is slick… but unfortunately a non-starter on ElastiCache by the looks of it.

If further information is needed to resolve the issue, would be glad to help out.
