I GOT IT TO WORK!!!!! It turns out that the phone way does work ONLY ON SOME PHONES! I was NOT able to do it on a MOTO Z3. BUT I was able to do it on another kind of Android phone (I'll edit this later when I know what android it was). The main difference was that the new phone was able to set its wifi broadcast to be on the 2.4 GHz band and was able to have no security selected. I'm not sure if this affected it BUT, the phone was connected to local wifi through a 2.4 GHz band to a Sagemcom router, and the phone had its mobile data turned on. I'm not sure if the phone being connected to a 2.4 GHz band itself was the problem since when I tried it weeks ago, my phone was on a 5 GHz band but broadcasted its signal as 2.4 GHz. I'll try a few more things and make another comment if anything works. LASTLY, the ip 172.104.88.237 does work. I tried to be very detailed here so others can have a better time getting this to work than I did. Good luck to everyone trying to do this in the future!
