Thanks for the advice, but it was something much sillier. I had tried both the default getInstance() and specified the IP address (I had looked at the code and saw they were both the same anyways). One issue was the router assigning my coding laptop the IP address "10.0.20.11", which makes me wonder why I was able to get any feed at all, and may explain why I got no feedback to the console after the error. The second issue was that one of the other mentors changed the password without telling me. After fixing both of these, it worked flawlessly!
I also saw the error again while working on it, and copied it so anyone else who sees this error might check those two problems for a fix
Code:
