internal communication in railway not working.

I am trying to deploy a laravel application in docker. Due to certain requirements I need to deploy it in two containers. one laravel container which runs php-fpm and another one is nginx server. I have enable private network for both the containers and I named the fpm contanier private domain app. Now if I use app:9000 in the proxy pass it is not working getting host not found in upstream "app" in /etc/nginx/conf.d/default.conf:30 error. everthing works for me in local. can someone help on this ?

may i ask why you cant run php and nginx in the same container?

Karthick K•5mo ago

i am planning for a load balncer config so i need to run cron job and queue using the same code but different containers do you think nginx:stable-alpine is a problem here ?
