I only have this issue on a Digital Ocean box. On my laptop I can see the website. On production I get 500 when trying to curl my site. if i hit the gateway of that docker from the outside world, i can see my site. but that's not a solution. i would like to point my dns to the ip of the host and not the docker gateway.
dockerfile
