Zookeeper client not connecting

I'm trying to connect with the client to Apache Zookeeper 3.8 using WSL (windows sub system) and

when I run bin/ZkCli.sh I got Connection refused

Here is the output:

Welcome to ZooKeeper!

Can anyone suggest something?

I resolved. I realized that I did not configure my conf/zoo_sample.cfg

I renamed the zoo_sample.cfg to zoo.cfg

Then I changed the dataDir to

dataDir=/mnt/c/testes/apache-zookeeper-3.8.0-bin/logs

then I ran server again using sudo bin/zkServer.sh start

And sudo bin/zkCli.sh

It worked!
