I'm unsure as to what happened, but I am unable to run sudo apt update on my rpi 4. I believe this problem came into play after I installed plex via this tutorial. I have looked in /etc/resolv.conf and it shows that my only nameserver is, but I have read this is normal after installing PiHole (which I have as well). The output of ping google.com is as follows, and from what I can make of it (which may not be much), it looks okay. I'm unsure what to do from here
