It is impossible for us to know what could go wrong based on your description. If you want support, you'll have to provide more details. Please create a small sample from start.spring.io where you connect to redis successfully prior to Spring Boot 3.4 that then fail when you upgrade to 3.4.

@f981545521 thank you for trying to help but code in text does not form a sample. If you want us to consider it, please share an actual sample we can run. You can attach a zip file here or push the code to a GitHub repository.

I also encountered this issue, but as suggested by @clinker, manually upgrading to version 6.5.1 can resolve it. The 6.4.1 version currently used by 3.4.1 may have some problems.
