So in my case it turns out I needed to update my unraid connect plugin. From the plugins screen it did not show an update was needed. However from the ca screen I clicked update and then after that upgrading to 7.2 was very smooth.

@ljm42 was correct, I failed to paste in the part about the unraid connect plugin in the error because at the time I did not realize it was relavent.

I figured this out on my own,
I went to unraid settings, stopped docker, and then checked the box for custom data network br0
