    I have been solved this, by making changes in the scale grid Redis cluster.

    just for other developer's context, make sure that you have created new cluster without -- tls after making this change connection won't get refused with the wp-cache object plugin.

    also as per the https://help.scalegrid.io/docs/redis-cli-tool-installation-use document make sure that you can able to make a connection with sg-cli.

    ScaleGrid has a blog post to address just this use case: Using Redis
    Object Cache to Speed Up Your WordPress Installation    . Does this help?

    From the article, this is the minimal configuration required.

    define('WP_REDIS_HOST', '<your-ScaleGrid-Hostname>');
define('WP_REDIS_PASSWORD', '<your-ScaleGrid-Password>');

    A good starting point would probably be strip your configuration file to just this, and see if that helps?

    Other than that, there isn’t much information to go on. The error seems to
    indicate a network error – have you verified if network connectivity is
    proper? One option would be to install redis CLI on your WP machine and attempt connecting via it. That would help narrow down if the issue is with PHP/WordPress or connectivity/configuration

    You could also check the logs on the Redis server side to check for any errors. If you haven’t already, maybe reach out to [email protected] so they can debug this for you?
