Connection refused about nginx-certbot

[AmanL04]

My setup: Running with upstream node apps.

The error I was getting when I ran ./init-letsencrypt.sh was always "Challenge failed for domain <domain-name>"

So I first mounted the nginx access and error logs to a volume and it always showed 1 of 2 things

1. nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/<domain-name>/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/<domain-name>/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
2. nginx: [emerg] host not found in upstream "auth" in /etc/nginx/sites-enabled/default.conf:13

-> The certificate error made sense as it did not exist and hence this error occured
-> The upstream error was the one I kept ignoring thinking it was due to certbot or nginx. But this in reality was the real error.

SOLUTION

My nginx server had no clue about the "auth" upstream as it would only be available when my docker service - "auth" would be up. So after a lot of ignoring the error, I just ran docker-compose up before the script and then ran the script.

Voila solved my issue.

Hope my stupidness helps others hours of googling. Cheers!

Hi, I have the same issue, how did you managed to correct it?
My NGINX Docker runs but impossible to have it accessible even though ports 80 and 443 are open.

Having the same issue as above @melvinmajor

I'm also getting similar errors.

I have no more "example.org" in any of the files
I'm only testing for a single domain pointing to a static IP on a linux EC2 server where I run docker-compose
I've tried the exact steps in the medium tutorial, and I've taken the latest code from the github repo.
I've tried it with the proposed nginx server, and with my own set-up of my server which, if run by itself, works (but only over HTTP)

I have the feeling the server with docker-compose doesn't start correctly. But I have no idea how to check this or how to fix it
