Connection refuse redis with docker image since java with spring-boot

I have the following question that I have not managed to solve, I have the following images running in docker: images list

In order to run my redis image I use the following command:

docker run --rm -d --name redis --net twitter -p 6379:6379 redis:6.0

I have a custom image, which is an application made with springboot and kotlin, the configuration file is a yaml, attached the configuration of my yaml file as well as the command that I use to run my image

File application.yaml

spring:  redis:    host: localhost    port: 6397server:  port: 9090

Command run:

docker run -d --name hashtag-tracker --net twitter -p 9090:9090 abahafart/tracked_hashtag

Remaining my images as follows: images list

My networks:networks list

Now when I curl, I get the following:

curl -H "Content-Type: application/json" -X POST -d '{"hashTag":"java","queue":"java"}' http://localhost:9090/api/tracked-hash-tag/add

I get:

{"timestamp":"2020-05-14T01:45:39.875+0000","path":"/api/tracked-hash-tag/add","status":500,"error":"Internal Server Error","message":"Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to localhost/<unresolved>:6397","requestId":"09e036ea-1"}

Viewing the image log:

Any idea why I can't connect?
