Slow outgoing HTTP Requests | Railway | Page 1

Hi,

I am experienced issues with really slow outgoing HTTP requests. If I run my application locally everything works well and is fast. But the app on railway really struggles and I've had to increase the HTTP request timeout to 10 seconds.

Sometimes things go through fast, but very often I get timeouts.

#

The service that makes http requests is chr-listener

#

are we talking about uploading data from local to your app running on railway?

#

Nop, the service itself is struggling with egress http calls.

Calling rest endpoints of external services outside railway.

#

what language?

distant abyss Apr 26, 2023, 6:09 PM

#

It's a nodejs application, axios.

cinder nova Apr 26, 2023, 6:13 PM

#

thats very odd, ive never had any issues with making api calls to external services, maybe this is a bug with axios?

#

might wanna try switching to the fetch api that comes std with node 18

#

Yea I mean I thought it was weird as well. But everything runs so smooth locally, I only see the issue on railway.

#

might also be an issue with the base ubuntu images nixpacks uses, you can also try to use an alpine based node 18 dockerfile

distant abyss Apr 26, 2023, 6:15 PM

#

I could try fetch, I have a .nvmrc with 18.14.0 so I guess it should be quite straight forward.

cinder nova Apr 26, 2023, 6:17 PM

#

dont think that would get railway to build with node 18

distant abyss Apr 26, 2023, 6:18 PM

#

I had some issues producing a docker image with my pnpm workspace turborepo.

#

cool, I will try that then and check if that resolves the issue. Next step after that would be to try to docker again I suppose

cinder nova Apr 26, 2023, 6:20 PM

#

just asked the team if there is any type of bandwidth management for traffic away from the app, will report back

distant abyss Apr 26, 2023, 6:20 PM

#

Thanks!

#

Yea this service sends quite a few http calls, so would be good to know

cinder nova Apr 26, 2023, 6:27 PM

#

got my answer, theres nothing in that layer, no bandwidth management, proxy, etc. nothing

distant abyss Apr 26, 2023, 7:14 PM

#

okey, good to know thanks. I'll experiment a bit more with my side. I'll open a fresh ticket if I still struggle after trying both things.

cinder nova Apr 26, 2023, 7:25 PM

#

good luck! but you can keep this ticket 🙂

distant abyss Apr 27, 2023, 5:26 PM

#

Hey @cinder nova, I tried first new node fetch with node18 and it was the same issue.

I now converted it to a Docker service with node:18-alpine, but still the same issue.

#

I am not sure what to test next, probably I have to try to run the container in a separate cloud service, if its the same there then we at least know its not something related to railway.

cinder nova Apr 27, 2023, 5:29 PM

#

yeah go try fly with your dockerfile

#

if there's no issues then you got your new host

distant abyss Apr 27, 2023, 5:52 PM

#

Well good and bad news. Same issue in Heroku with same Dockerfile. So it should be something in the application. 🙂

At least I know where to continue dig now.
