Strange Error On Every Webpage Proxied Through Cloudflare & NPM

Can’t figure out why it says “cannot find address, chicago, il” at the top of all of my sites. This only shows up on iOS, using Safari/Chrome/Brave browsers. I have several services through Docker, exposed to the internet via NGINX proxy manager. When I visit the sub domains, this is at the top of each webpage. Imgur: The magic of the Internet
It goes away when I turn OFF the proxy feature in Cloudflare. Should I be concerned about leaving all these sites unproxied in Cloudflare?
