Still “Not connected” – although following all tips

PS: Also the WP-Backend really gets slow, after activating Redis Object Cache. Maybe because it cannot connect?

Can you post your diagnostics?

This is your error:

Connection Exception: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution (RedisException)
<code></code>

So using redis as your host doesn’t work. Try this:

define('WP_REDIS_HOST', '127.0.0.1');
define('WP_REDIS_PORT', 6379);

Yep, that did the trick! ??

Thank you so much, Till.

Perfect support.

All the best,
Johannes
