When connecting to Terraria server it stays on "Found server" indefinitely

Hey thanks for reading this post!

I’m using playit.gg to try and start a terraria server but everytime I try to connect to the server or one of my friends try and connect to the server it gets stuck on the “Found server” screen in terraria. I’ve made sure to hose the server on my desktop through TerrariaServer.exe but still no luck. I am using the normal TerrariaServer.exe and I’m not using tShock or anything. Do I have to use tShock in order to run the server?
