Terraria Found Server freeze Fix (server port being used issue)

In this video, I try to walk you through the process of the Terraria found server freeze. here are the reddits I used to identify and solve the problem. if the problem isn't port usage it won't display any line indicating usage of the port. For ex. in the video I call to port 7776 just to see if that port had been used and it didn't return me any values. This told me that port 7776 was not being used. if port 7777 is not being used this is not the problem and you can search for the answer elsewhere.
