Wordpress LScache Plugin: Redis not working if running on a separate server
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, Im using the DigitalOcean one-click install which comes with the plugin bundled. Im using a Managed MySQL DB to which I connect without a problem through the private network and a Managed Redis database as well. When I try to connect to Redis however, the plugin says Connection Test: Failed . Does it not work properly when Redis is running on a separate server? I have tried both through the public and private networks. I can do the following as mentioned in the DigitalOcean docs to test and connect to the redis server without a problem: telnet HOST PORT But the plugin still says the test failed. I have added the Host, Port, User (though the plugin says its only for LSMCD) and password. DB Id is set to 0. Any ideas what might be going wrong? Thank you.

It seems you also replied on DO, thank you! I was getting a 500 error, enabled error display and got: Fatal error: Uncaught RedisException: read error on connection to private-SERVER-do-user-NUMBER-0.a.db.ondigitalocean.com:25061 in /var/www/html/redis_test.php:8 Stack trace: #0 /var/www/html/redis_test.php(8): Redis->auth() #1 main thrown in /var/www/html/redis_test.php on line 8 The password on that line seems to be correct though. Hi, yeah ? please do not post same issue on multiple places then try with command line redis-cli -h 127.0.0.1 -p 6379 -a thisizmy!PASS change the datas to your own , and see if you can connect Best regards, My apologies, I didnt expect you to reply there as well. I posted there just in case it was an issue with DO. root@web-01:/var/www/html# redis-cli -h private-SERVER-do-user-NUMBER-0.a.db.ondigitalocean.com -p 25061 -a password Warning: Using a password with -a or -u option on the command line interface may not be safe. private-SERVER-do-user-NUMBER-0.a.db.ondigitalocean.com:25061> It looks like it can connect without a problem. Screenshot of my settings: https://i.imgur.com/ROzTg5T.png in your screenshot , username should be empty The problem persists with or without user there. Hi, based on your reply in DO, this is more like PHP issue instead of plugin issue , lets keep conversation there then. Best regards,
