Unity Transport - Issues with Client/Server connections in 2020.2

I'm trying to use Unity Transport in my project on 2020.2. The client never seems able to connect to the server even on localhost. Additionally, I've tried the ping sample in the multiplayer github repo and that does not seem to work properly either.

 

I'm using UT in 2020.2 and it works fine. Make sure you're doing everything as intended in https://docs.unity3d.com/Packages/com.unity.transport@0.6/manual/samples/serverbehaviour.cs.html and https://docs.unity3d.com/Packages/com.unity.transport@0.6/manual/samples/clientbehaviour.cs.html
