If you receive the error message 'could not connect to redis name or service not known', it implies that your Redis client failed to establish a connection with the Redis server. The possible reasons behind this could be an incorrect hostname or port number settings, issues with network connectivity, or firewall restrictions that are blocking access to the Redis server.
This error can occur due to several factors such as incorrect IP address or hostname specified in the Redis client configuration, Redis server not running or listening on the designated port, network connectivity problems, or firewall restrictions blocking the Redis server's port.
To resolve the 'could not connect to redis name or service not known' error, begin by checking the IP address or hostname and port number specified in your Redis client configuration file. Ensure that they match the current settings of the Redis server. You can verify these settings by looking at the Redis server's configuration file or contacting your system administrator.
If the Redis server is not running or listening on the assigned port, you will need to start it manually or configure it to start automatically. You can use Redis CLI commands like
redis-cli ping to check if the Redis server is running and responding.
For network connectivity issues or firewall restrictions, contact your network administrator to allow access to the Redis server's port. If that doesn't work, try changing the Redis server's port to a different one that is not blocked by the firewall.
