Application Error Is your app correctly listening on $PORT? Django Application

[twin socket]

I'm trying to deploy a django application, during the procedure no errors are reported, but when I access the link the website returns the following error: Application Error Is your app correctly listening on $PORT?
I ping the site by the url and I got a response.
The migrates were run without problems, including the data has already been restored in the database.

Has anyone had a similar problem?

make sure that you have set your PORT environment variable in the project to whatever your django app is listening on (default is 8000 iirc)

also, it looks like in the deploy logs it never started? it just ran migrations. it should say something about starting up and listening on 0.0.0.0:8000

[twin socket]

there is no message in deploy log

[brave cape]

in the message you sent above there is, is this a fresh redeploy?

[twin socket]

No. It's the same deploy

[brave cape]

ok, then just make sure you have the PORT environment variable for your project set to 8000 or whatever you have Django configured to use

[twin socket]

it's already set.

I tried to run the command "railway run" in the start command but it returned an unknown command error "railway"

[brave cape]

when the project deploys you try to run railway run? that won't work unless you set up railway-cli inside the image. you should just be able to remove railway run from whatever you are trying to run, since it's already on railway and has access to the environment variables that would be exposed if you ran railway run ... locally

[twin socket]

I'm trying various suggestions to try to solve this port problem.

Port 8000 is already set in the django application settings

[brave cape]

yes but you need to set it on railway as well, in the project environment variables

[twin socket]

is already configured too

[brave cape]

so then you just need to make sure that your django project is actually up and running, there should be something in the deploy logs.

if possible could you send me a github repo? perhaps it's something with the configuration preventing it from starting properly

hey Jackson,
I am also facing the same error.
facing this issue from last 4 days, unable to make it up.
please guide

rest of the things are working completely fine

[brave cape]

in this case i think you need to set default_addr to 0.0.0.0

if that doesn't work, please make a new help thread with screenshots of deployment logs & error messages if any

[amber whale]

ok.
thank you

@twin socket , did you get any luck ?

[twin socket]

not yet. I put in the start command the command 'python manage.py runserver 8000' and returned the following message

[amber whale]

have you done this?

[twin socket]

Not yet. I'm not in front of the computer anymore. As soon as it is, I'll try. In allowed_hosts there is only the address xxx.up.railway.app

[twin socket]

I made the changes you suggested in settings.py and it remains the same.

If I run the command "python manage.py runserver 8000", the server returns the error "Application Error Is your app correctly listening on $PORT?"

If I run the command "python manage.py runserver 0.0.0.0:8000" the log gives me the error "INFO "GET / HTTP/1.1" 301 0"

don't manually set $PORT

i believe railway provides it

[raw orchid]

i deployed my app with this nixpacks.toml config:

cmd = 'python manage.py migrate && gunicorn -b 0.0.0.0:$PORT --max-requests 1000 --workers 5 --threads 2 [appname].wsgi'```

[twin socket]

it didn't work either. Still with the same errors:
"Application Error Is your app correctly listening on $PORT?"

[raw orchid]

do you see this?

[twin socket]

do not. my log stops at no migrations to apply

[raw orchid]

go to your build logs, what do you see here?

[twin socket]

Only this

[raw orchid]

oh hmm

i domt have much experience with dockerfile configs

[shy thistle]

Please send your github repo

Looks to me like you have a dockerfile in there that’s messing everything up

[shy thistle]

This is not your thread, please make your own for your question

[twin socket]

I deleted the application to send it again without the dockerfile and docker-compose.yml files and it always returns the same error.

[shy thistle]

please send your repo

[twin socket]

I can't share the repo with you because of work regulations, but if you tell me the excerpt you'd like to see, I'll copy it and send it to you.

[shy thistle]

I’d like to see the contents of your dockerfile as well as your root directory. If you have a nixpacks.toml or railway.toml i’d like to see that as well
