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: http://supershot.click/

I ran this command:

It produced this output: 502 bad gateway

My web server is (include version): nginx/1.18.0 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 20.04.6 LTS (GNU/Linux 5.15.0-1030-aws x86_64)

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):

What makes you think the problem is related to your SSL certificate? SSL/HTTPS appears to be working just fine on your server.

I would guess that the 502 has some unrelated cause.

This normally means your web server is configured to pull it's content from something else (reverse proxy), like another application server on the same machine or a different machine. If that other service stops running then your nginx can't proxy that information anymore.
