The redis connection is down

[hogger0]

My redis is stand-alone version: 7.0.4.
The springboot version is 3.2.8.
The spring gateway service is connected to redis. If there is no operation for a period of time, Every 15 minutes or so and redis will disconnect the link and the console will report an error of connection reset. How is this caused? Do you need to modify the configuration of redis or spring?

redis:
host: 192.168.146.123
port: 6379
password: 123456
timeout: 5000ms

Looks like some component between your application and Redis is disconnecting your connection. Sounds like an infrastructure issue.
