This exception is thrown when Spring Data Redis is unable to connect to a Redis server. There can be several reasons why the connection fails, such as:
1. Incorrect Redis server address or port number.
2. Redis server is not running.
3. Firewall or network issues that prevent the connection.
4. Authentication failure if Redis server is configured to require a password.
To resolve this issue, you can try the following steps:
1. Verify that the Redis server address and port number are correct.
2. Check whether Redis server is running using the command `redis-cli ping`. If it returns `PONG`, it means the server is running.
3. Check firewall settings and ensure that the Redis server port is open.
4. If Redis server is configured to require a password, ensure that the correct password is provided in the Redis configuration.
If none of these steps resolve the issue, it might be helpful to check the Redis server logs for any errors or warnings.
