I created a socketio flask rest api and it works great locally for retriving and sending data through the websockets, but as soon as I upload my code onto the railway server, the server doesn't work with my websockets. Is there any special configuration I need to do?

we are going to need more information than "the server doesn't work"

#

The error I provided is all that is shown in my logs

#

are you using gunicorn when on railway?

abstract rampart Jan 9, 2024, 6:30 AM

#

yeah:
web: gunicorn main:app

warped fog Jan 9, 2024, 6:31 AM

#

have you confirmed it's working locally when starting your app with that command?

abstract rampart Jan 9, 2024, 6:34 AM

#

Just tested it, it doesn't appear to work, so im guessing its an issue on my side

warped fog Jan 9, 2024, 6:34 AM

#

does gunicorn even natively support websockets? maybe you want to use Daphne instead?

abstract rampart Jan 9, 2024, 6:34 AM

#

I'll check right now

warped fog Jan 9, 2024, 6:37 AM

#

I think the start command for Daphne would be

daphne main:app --bind 0.0.0.0 --port $PORT

so add daphne to your requirements.txt and then update the web command in your Procfile to that command above

well the things ive already said would apply to you, so give daphne a try

I user geventlet and it started working (with gunicorn)

#

This is the command:
web: gunicorn --worker-class eventlet -w 1 main:app

#

abstract rampart This is the command: web: gunicorn --worker-class eventlet -w 1 main:app

Will this be considered a good solution?

#

Will we be able to use both HTTP and TCP traffic?

warped fog Jan 12, 2024, 2:50 PM

#

since when did gunicorn without geventlet support tcp??
