Error: spring boot redis health check failed

What's Causing This Error

The error "spring boot redis health check failed" typically occurs when a Spring Boot application is unable to connect to Redis server. There could be several reasons for this failure, such as incorrect configuration, network connectivity issues, or Redis server being unavailable.

One of the common reasons for this error is misconfiguration of the Redis connection properties in the application's configuration file. This can include specifying an incorrect host or port number, using the wrong password, or providing invalid SSL configurations. Another reason could be that Redis is not running on the specified host and port, or there are network connectivity issues preventing the application from communicating with Redis.

Solution - Here's How To Resolve It

To resolve the "spring boot redis health check failed" error, we first need to identify the cause of the problem. If the issue lies with the configuration property, it is important to double-check that the host, port, SSL configurations and password are correct and match those of the Redis server. If the Redis server is running on a different machine, ensure that the machine is accessible from the application server.

If the configuration appears to be correct, it may be necessary to investigate network issues. Check if the Redis server is up and running on the specified host and port by attempting to connect to it through a Redis client tool. If Redis is not running on the specified host and port, start the Redis server or change the configuration to point to the correct host and port.

Finally, if network issues persist, consider checking firewall settings or other network security measures that may be blocking communication between the application server and Redis server. By troubleshooting these potential causes, we can successfully resolve the "spring boot redis health check failed" error and establish a stable connection between the Spring Boot application and Redis server.
