do you have any logs for when you get the error page?

what kind of app?

no logs, I just can't reach the server so there's no logging

it's a fastapi backend

right but if your application was erroring and not responding, ideally there would be logs

all of the 0s are downtimes

It looks like it's railway that's not responding

```

Nothing here… yet

Application failed to respond

    <a href="https://railway.app"> Go to Railway </a>
```

No error from my app

that page is shown when your application doesn't respond

are these https requests? what am I looking at here?

The server soetimes works and sometimes doesn't without any changes from my side

Yup, this is in postman

I'm calling the backend hosted on railway

do you have a custom domain?

I understand how it sounds but that does not rule out an issue with your app

it also does not rule out an issue with railway, but from experience it's more often an issue with the application

Yes I have a custom domain

How to debug if it's railway or my app? It works perfectly locally

My other friends also have uptime problems with railway and have migrated to render

unfortunately working locally does not rule out an issue with the application either

do you have the edge proxy enabled?

What's edge proxy? Is this from domain side (e.g. namecheap)

it would be in the service settings

Should I enable this?

yes, but first, you said your domain provider was namecheap?

yes

are you sure you are using the correct generated cname it gave you when you set it up?

yes it's been assigend to this domain name for months

I'm sorry but that answer does not instill confidence, I would like to ask for confirmation

yes I'm sure

you are using the generated cname, not the auto generated domain, correct?

Yes

go ahead and enable the edge proxy

Done, what should I do next?

wait and see if you continue to have issues

When should I check back in? Just tried postman and still have the same issue

what's the state of your deployment

deployed

I'm sorry but that's not a valid state

yes, please tell me it's state

What does that mean?

it's deployment state

Completed?

your app has exited

this would not be a platform issue

Where do you see that the app has exited

completed

How do I fix it?

first, let me correct myself, the edge proxy is not going to help here, I had asked you to make that change without enough information from you.

second, since this is an issue with your application I would recommend implementing error handing everywhere and verbose logging to help you narrow down the issue.

remember, railway only ever runs your code as-is, so if it's exiting that's something your app is doing, not the platform

What does it mean for the app to have exited?

The app bugged out and shut down?

the app exited with a non error code for (at this time) an unknown reason

Hmm I see, I'll look into it

thanks

I wish you the best of luck in your debugging endeavour

Is it possible it exceeded resource constraints? Is there some way to check for that?

you think your app could have exceeded 32gb of ram?

We run a 100M parameter LLM model, 32b should be enough

what do your memory metrics look like?

Hmm goes up quite high

have you received any emails from railway that state you ran out of memory?

Nope these are the latest emails

then it doesn't seem like that's the issue

What does completed mean? This deployment is "completed" instead of "active" but up and running, have healthy logs

Completed is when you exit using a 0 exit code. However, going to raise this to the team for investigation.
