Thanks for getting back to me. I was using Root credentials, I had everything connected.
I installed mitmproxy using apt get install mitmproxy.
it installed the 3 parts to it (web, mitmproxy, dump) and when I ran web it created an address that took me to the webpage. But nothing came up.
I tried running MITMproxy first, still nothing showed up.
I feel like maybe I need to enable IPV4 Port forwarding?
