Hey @samerkassem82 , I can't seem to reproduce this error, I am using a mac laptop - which os are you on?

I am encountering a similar issue, but I get the following error:

Failed to proxy http://undefined:12883/__next_devtools__/client 
Error: getaddrinfo ENOTFOUND undefined
    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:120:26)
    at GetAddrInfoReqWrap.callbackTrampoline (node:internal/async_hooks:130:17) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'undefined'
}

Is it possible to manually set the address somewhere to resolve this undefined?

I use address ip('lo') to get the host, but I don't know why it returns undefined

Currently using localhost as a fallback.
