It's not my first time using this keg. I have taken it apart before and it looked ok. It has a new o ring on it but I can try switching that out again. Thanks for the help and the responses. Below is the video. I filled it with water because no one ever wants to waste beer you can see it leaking when the disconnect is attached.
I'm going to take the post apart again and put another new o ring on and see if that helps.
