Asked by Quenoz Alvareoe
I have this droplet that I served as staging instance and has network firewall on it. As it is a staging instance I made it work like a private access only by adding our outline vpn ip on http and https port, everything is working except when validating website with certbot and github action not able to connect to the droplet instance. How do I whitelist the github and certbot? Any help, suggestions, recommendations is greatly appreciated!

Hey @julivergalleto,
It’s either you allow access on port 80 and 443 or you find the certbot and Github IP ranges and allow them.
Regarding Github ranges you can check this link here:
https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/about-githubs-ip-addresses
As for allowing Certbot, I found this topic that could be of help:
https://community.letsencrypt.org/t/lets-encrypt-server-addresses-for-certificate-renewal/83466/2
Nothing else of significance that I could find.
