Redis connection timeouts and unreachable error
-
Hi, firstly, thanks for your plugin. I use it on multiple sites, and it worked great until the recent update. After upgrading to v2.4.1 we have the same issue as mentioned in the already resolved topic. We connect over TLS and ACL (username, password) to our Redis cloud instance. The status also says connected, but not reachable. But instead of the error mentioned in the linked post above, we get the “Redis is unreachable: SELECT failed: NOAUTH Authentication required.” error like mentioned in this post. This has several side effects, so I had to disable the object cache for now because we have high traffic in our shop:
- Sometimes the users see a “Redis unavailable” error page, but after reloading it’s gone
- Some WooCommerce orders are created twice in the same second, inclusive their payments
- The product, order, payment sync with the JTL-Connector Plugin is blocked because of the issue mentioned first. This blocks syncing products, prices and inventories.
Below my diagnosis after disabling the plugin (I blacked out some connection data):
Status: Not enabled Client: Drop-in: Not installed Disabled: No PhpRedis: 5.3.7 Relay: Not loaded Predis: 2.1.2 Credis: Not loaded PHP Version: 7.4.33 Plugin Version: 2.4.1 Redis Version: Unknown Multisite: No Metrics: Disabled Metrics recorded: 0 Filesystem: Working WP_REDIS_DISABLED: false WP_REDIS_SCHEME: "tls" WP_REDIS_SSL_CONTEXT: { "verify_peer": false, "verify_peer_name": false } WP_REDIS_HOST: "vultr-prod-vultr-prod-3165.vultrdb.com" WP_REDIS_PORT: 16752 WP_REDIS_DATABASE: 0 WP_REDIS_PREFIX: "my-prefix" WP_REDIS_PLUGIN_PATH: "/srv/www/thehoneyfactory.de/releases/20230514203445/web/app/plugins/redis-cache" WP_REDIS_PASSWORD: ["my-user","••••••••"] Drop-ins: [ "advanced-cache.php v by " ]I can’t enable it right now, but the diagnosis was something like:
