Redis server
There could be several reasons for this exception:
1. The Redis server is not running or is not accessible from the network.
2. The connection parameters (host, port, password) are incorrect.
3. A firewall or network configuration is blocking the connection.
4. There are too many connections to the Redis server, and it has reached its maximum capacity.
5. The Redis server is experiencing a temporary failure or outage.
To resolve this issue, you can try the following steps:
1. Make sure the Redis server is running and accessible from the network. You can test this by using a Redis client or a telnet command to connect to the Redis server.
2. Verify that the connection parameters are correct. Double-check the host, port, and password values in your connection configuration.
3. Check your firewall or network configuration to ensure that it is not blocking the Redis connection. You may need to open specific ports or allow certain IP addresses to connect to the Redis server.
4. If you are experiencing too many connections, you may need to increase the maximum capacity of the Redis server or reduce the number of connections to it.
5. If the Redis server is experiencing a temporary failure, you can try restarting it or waiting for it to recover.
