I stop and start the docker container, but it doesn't work. Docker Image is redis:alpine3.14. (The docker is installed in WSL1)

Comment From: itamarhaber

Doesn't reproduce with the redis:alpine3.14 image as well.

This may be a problem only on my machine. If no one has similar problems, it will be turned off in a few days. Thanks~
