Private Networking ECONNREFUSED

Question

I am trying to reach my Hono backend from my NextJS app using private networking, but on every HTTP request I get this error in my NextJS app:

```error TypeError: fetch failed

at async h (.next/server/app/(routes)/(main)/page.js:1:1795) {

[cause]: Error: connect ECONNREFUSED fd12:c7f1:d3cf:0:2000:16:4e81:67b6:80

at  (Error: connect ECONNREFUSED fd12:c7f1:d3cf:0:2000:16:4e81:67b6:80) {

errno: -111,

code: 'ECONNREFUSED',

syscall: 'connect',

address: 'fd12:c7f1:d3cf:0:2000:16:4e81:67b6',

port: 80

}

}```

Using public networking works perfectly but I want to switch to private 😢
