Dev server detected!

jeOP•8mo ago

thats why?

Your app needs to use 0.0.0.0 as the host ( like the message box at the top says ) You're also running a development server, you'll want to use gunicorn to run your server to do that, add gunicorn to requirements.txt your start command would look something like this gunicorn main:app -b [::]:5000 ( you can set it in service settings )

jeOP•8mo ago

alright let me try it

Brody•8mo ago

gunicorn main:app

gunicorn main:app

will suffice in most cases

so yea i did both of what you guys told me into my start command and it gives out this it worked but I have a discord bot with it but its not loaded?

right here before it said discord logging in

Brody•8mo ago

a discord bot with a flask app? may i ask why?

jeOP•8mo ago

because im hosting a dashboard with it also and this will really help me out

Brody•8mo ago

you would need to start the discord bot in async mode

jeOP•8mo ago

ah I have it like this

def run_flask():
    app.run(port=5000)


def run_discord():
    bot.run(TOKEN)

if __name__ == "__main__":
    flask_thread = threading.Thread(target=run_flask)
    discord_thread = threading.Thread(target=run_discord)
    flask_thread.start()
    discord_thread.start()
    flask_thread.join()
    discord_thread.join()

def run_flask():
    app.run(port=5000)


def run_discord():
    bot.run(TOKEN)

if __name__ == "__main__":
    flask_thread = threading.Thread(target=run_flask)
    discord_thread = threading.Thread(target=run_discord)
    flask_thread.start()
    discord_thread.start()
    flask_thread.join()
    discord_thread.join()

how do i fix it?

Brody•8mo ago

Im sorry but we wouldnt be able to offer coding help here, these help threads are meant to provide platform help

jeOP•8mo ago

ah okay

Brody•8mo ago

get it working locally with gunicorn and then we can can pick back up on this

jeOP•8mo ago

isnt it already

jeOP•8mo ago

Brody•8mo ago

is the discord bot running?

jeOP•8mo ago

nope

Brody•8mo ago

then my statement stands

jeOP•8mo ago

okay may you please help out, i still dont understand how gunicorn is blocking it

Brody•8mo ago

Im sorry but we wouldnt be able to offer coding help here, these help threads are meant to provide platform help

jeOP•8mo ago

yea i see why now when i remove gunicorn main:app from the start command it goes back to dev and loads the discord bot

Brody•8mo ago

you need to use gunicorn to run the flask app when on railway

jeOP•8mo ago

do you know how i can allow the discord bot also?

Brody•8mo ago

again, sorry but we would not be able to offer code help here

jeOP•8mo ago

no im asking what else do i put on the start command

Brody•8mo ago

nothing to do with the start command, this would be a code issue
