Nginx exiting because he can't find privkey and fullchain, but they exist

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
www.posology-api.com
I ran this command:

It produced this output:

My web server is (include version):
Nginx:latest
The operating system my web server runs on is (include version):
Ubuntu 22 EC2
My hosting provider, if applicable, is:
AWS
I can login to a root shell on my machine (yes or no, or I don't know):
Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
No
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
1.32.2

So I created standalone certificates since as it seems you need to have a PhD in something to be able to get a bloody certificate for your domain, I still don't know why is this so complicated. I've got the files, they're located properly in /etc/letsencrypt/live/mydomain.com, I double checked that, also my docker-compose and nginx.conf are properly configured but once I up my application, nginx cries how he cant find the files that exist. Anyone has a simple solution/fix for this?

That contradicts:

I would think the problem is within the complexity of your setup.
Which seems to...

I would simplify it wherever possible.

I'm not sure how you got to where you are.
But I'm pretty sure neither LE nor certbot put you on that road.

Could it be a permission issue? It's a fresh EC2 machine, haven't messed with pem file permissions at all..

Anything is possible at this point...

Can you list those files from within the nginx container?

Try these:

docker exec -it nginx ls -l /etc/letsencrypt/
docker exec -it nginx ls -l /etc/letsencrypt/live/posology-api.com/

Sorry for late reply, I managed to solve it. I did use that init-letsencrypt.sh script everyone is telling it wrong, but as I cloned that guy's repo and executed the script, it went through and I just copied the 'data' folder to my project, ran docker-compose up and my app is now up on a https. Thank you for your time mate :slight_smile:
