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: stomp.textras.com
I ran this command: sudo certbot certonly --standalone
It produced this output: I don't recall, it was 3 months ago
My web server is (include version): cowboy v2.x (i haven't found the exact version of cowboy but I've confirmed that it's in the v2.x range)
The operating system my web server runs on is (include version): ubuntu 18.04
My hosting provider, if applicable, is:
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): certbot 1.26.0
Auto-renewal is not working for me. I initially installed the cert using sudo certbot certonly --standalone and it worked, but after 3 months the cert expired without renewal. I'm using the cert for tls on a rabbitmq server running in a docker container, so I had to create a mount volume that allows the running server in the container to access the cert installed on the host system. Manually renewing the cert works, but when I do a dry-run to test renewal I get this:
Failed to renew certificate stomp.textras.com with error: Could not bind TCP port 80 because it is already in use by another process on this system (such as a web server). Please stop the program in question and then try again.
Of course the rabbitmq server is running and using port 80, and when I manually renewed I had to stop the docker service entirely to perform the renewal. How can I handle this? Is there a way to configure the autorenewal steps and modify the commands so it gracefully shuts down the docker service, performs the renewal, then restarts the service?
