Web Server Not Working

I just started a small simple web server. I generated a custom domain for now, and when trying to access it I'm being met with Application failed to respond

5cbfb706-f70d-4814-9834-3f94646c5518

did you use env.PORT for your port?

No I just used 3000 hard coded

You should use env.PORT then
only works if you use the port railway provides

If you used 3000 hard coded, set env variable of PORT to 3000 in your service

oh you can do that?

ok

Yup

is that new?

Nope

dang

It's better to listen on the port provided, but if you specify it in your code or if it's a docker image, you can set it manually

so wait am I able to just not create a port variable on railway

Yes, you can create an environment variable in your service and call it PORT and give it the value of 3000

Okay thank you
