Tyk Redis is either down or not configured

If the gateway log level is a warning then you can ignore it as suggested on this thread

However, it appears the gateway log level is an error as seen from the result of your shared gateway health status.

{“status”:“fail”,“version”:“v4.0.0”,“description”:“Tyk GW”,“details”:{“redis”:{“status”:“fail”,“output”:“storage: Redis is either down or was not configured”,“componentType”:“datastore”,“time”:“2022-07-14T08:41:59Z”}}}

This simply means that there is an issue with your Redis and it’s either down/not started. Or it has not been configured with the gateway. To resolve, kindly check the gateway storage configuration. Here is a sample of what it should look like

{
...
"storage": {
		"database": 0,
		"enable_cluster": false,
		"host": "tyk-open-source-redis",
		"hosts": null,
		"optimisation_max_active": 5000,
		"optimisation_max_idle": 3000,
		"password": "",
		"port": 6000,
		"type": "redis",
		"username": ""
	}
}

Another issue that maybe occurring is Redis cluster misconfiguration.
