socket.gaierror: [Errno -2] Name or service not known

I have a hypercorn app but am encountering this error: socket.gaierror: [Errno -2] Name or service not known. It works when I specify a railway.json that specifies a port, but only on a local host, not on the public domain. How can I fix this?

{
    "deploy": {
        "startCommand": "hypercorn main:app --bind \"0.0.0.0:8000\""
    }
}

{
    "deploy": {
        "startCommand": "hypercorn main:app --bind \"0.0.0.0:8000\""
    }
}

you want to use

hypercorn main:app --bind [::]:$PORT

hypercorn main:app --bind [::]:$PORT

Dem•5mo ago

Hmm same error:

sock.bind(binding)

socket.gaierror: [Errno -2] Name or service not known

sock.bind(binding)

    }
}

    "deploy": {
        "startCommand": "hypercorn main:app --bind [::]:$PORT"
    }
}

might need to escape some of it

hypercorn main:app --bind \"[::]:$PORT\"

hypercorn main:app --bind \"[::]:$PORT\"

Dem•5mo ago

hmm that's odd, is that not how it written here? https://github.com/vfehring/fastapi/blob/main/railway.json#L7 if it was wrong we absolutely would have heard of it by now

Dem•5mo ago

I can try ading the schema and build fields?

Brody•5mo ago

nah that's not the issue

Dem•5mo ago

Should I ingore this error

Brody•5mo ago

share your repo? replace the railway.app domain with schema.up.railway.app and the error goes away

Dem•5mo ago

Are you able to view this? https://github.com/onjas-buidl/GPTs-ads-backend

Brody•5mo ago

nope

Dem•5mo ago

Let me try the new railway json Same thing

Dem•5mo ago

This is what my repo looksl ike

Brody•5mo ago

delete the procfile that's a heroku thing mainly

Dem•5mo ago

Brody•5mo ago

also I'd like the build logs https://bookmarklets.up.railway.app/log-downloader/ before you push this change

Dem•5mo ago

Oh I already pushed But it's the same error

how can you be sure that railway is using the correct start command?

Dem•5mo ago

Do you mean the hypercorn command?

Brody•5mo ago

yes

Dem•5mo ago

That works locally for me, maybe it's not the correct command for railway though

Brody•5mo ago

I mean, it works here for fastapi

Dem•5mo ago

When I hard code the port to 8000, it works on railway except I can't access the API on public domain Ya I'm using fastapi Yup

Brody•5mo ago

send your dockerfile?

This is what I get when I hard code to 8000, it runs the code but not accessible on public domain

Brody•5mo ago

may I ask what you are using chrome for?

Dem•5mo ago

it's for simulating user visits to our site was debugging something sorry

Brody•5mo ago

it not the ideal solution, hard code the port to 8000 and then set a PORT service variable to 8000

Dem•5mo ago

Got it, thanks!

Brody•5mo ago

let me know if that works

Dem•5mo ago

That worked! Thank you

Brody•5mo ago

no problem!
