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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

IMPORTANT NOTES:

The following errors were reported by the server:
Domain: pretalx.charmedhypno.org
Type: connection

http://pretalx.charmedhypno.org/.well-known/acme-challenge/P3d9SUdRUPxS_8utzgMzct3qgRL0nbB9b7FBqQjzEZA:
Timeout during connect (likely firewall problem)To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
My web server is (include version):
NGINX v1.14.0 (Ubuntu)
The operating system my web server runs on is (include version):
Ubuntu 18.04
My hosting provider, if applicable, is:
This is a VM instance running on Google Cloud
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): 0.31.0
The certificate has been working for 6 months, meaning one successful renewal, but it didn’t auto-renew this time and it expired today. It reads like it can’t get to port 80, but port 80 is open (and redirected) just as it has always been. Nobody futzes with this server – I had to look up my login credentials it’s been so long. What gives?
