How to avoid steam query port in UE4?

So I want to make a matchmaking system. I already have a manager set up which automatically starts servers. So I want to use steam as my authentication system. The problem is that the query port isn’t incrementing itself so the steam API won’t initialize.

My own subsystem is written with the VaREST Plugin.

As of right now, I can easily connect with one of my servers without steam. As soon as I turn on steam the server steam API shuts down and tells me my unique net id is incompatible (obviously).

To be clear I only want to use steam for authentication purposes (getting the name etc.) and NOT for a session system.

Any help is much appreciated!
