Never happened before, but today I upgrade Windows preview version, and an exception occured (Connection Refused: connect).

Redis runs in a Docker container and Docker runs in WSL2 (Ubuntu 18.04), and also there are a Mongodb database and a Mysql database running in docker. I cannot connect to Mongodb(by Java) or Redis (by Jedit) but Mysql is well (by Navicat or Java).

Then, I write a simple java program with Jedis to connect to Redis, it works failed in Windows but successful in WSL2. And I also connect to Redis with telnet command, it works successful in Windows and WSL2.

Windows Version: 10.0.20175.1000, Insider Preview, Build 20175.re_prerelease.200717-1349
Linux in WSL2: Ubuntu 18.04
Docker Version: 19.03.8
Mongodb and Redis: latest
Mysql: 5.6
Jedis: 2.7.2

    Welcome to Microsoft Q&A Platform.
    The latest Insider Preview version is just used for test potential bug and new functions, it’s normal to meet with issue, you could feedback this connection issue here
    https://learn.microsoft.com/en-us/windows-insider/at-home/feedback
    Now I suggest to roll back to preview version and continue using your java program in WSL 2, wait for update or RTM version from Microsoft.
