remoteAddr returning localhost on Deno Deploy

I saw this thread (helpHow do i get the IP address of a request in Fresh | Deno?) about getting the IP of the requester, but I'm not getting the value I expected.

I tried using

ctx.remoteAddr

ctx.remoteAddr

with Fresh on Deno Deploy and I get

{ transport: "tcp", hostname: "localhost", port: 1234 }

{ transport: "tcp", hostname: "localhost", port: 1234 }

instead of an IP address – is there something I need to configure to get "real" values?
