In my case, I have a local Redis Server 6 and Jedis connects using host=localhost or host=127.0.0.1 but when I try to do a jedis connection ping it throws the JedisConnectionException.
If you have the same behavior, check that your redis server is working. Connect with a redis-cli and execute a ping using same host and port that you have in jedis.
If you get a response "PONG" it is ok, but if you get something like "Connection reset by peer" you need to change your server binding.
After I changed the bind address to 0.0.0.0 it works for me.
An example using docker, Redis server 6 and redis-client:

- Run the Redis Server:
#!/bin/bash
MSYS_NO_PATHCONV=1 docker run -d --rm --name redis -p 6379:6379 -v $(pwd)/redis.conf:/redis.conf redis redis-server /redis.conf
- Run the Redis Client:
docker run -it --network=host --rm redis redis-cli -h 127.0.0.1
- Test the connection:
127.0.0.1:6379> ping
PONG
After that, check your jedis config to use same IP and port and this should solve the problem.
