New setup questions

Hey guys please be patient with me as I am new to this system. I am in the process of setting up my Nextcloud server on a Ubuntu 22.04 VM and obviously, to host it over the internet it needs a cert, and Lets Encrypt is integrated into the Linux package. I have several questions please.

  1. I have a No_IP account and host names to redirect to the static IP on the server can I use that instead of a Domain? Note: I do have a domain (Its a google domain)

  2. I did port forwarding for port 80 and 443 to the server but I have 2 web servers I want to host. This one and a Windows server for ticketing later on I know I cant port forward the same ports twice so what's the best setup for that?

  3. when trying to create the certs I get an error saying "The connection timed out " I believe this is because google takes a while to update the DNS A record. Does that sound right?

Thank you guys so much for your time!

My domain is: nextcloud22.net

Hello @computermaster18, welcome to the Let's Encrypt community. :slightly_smiling_face:

Best Practice - Keep Port 80 Open

No IP Ports are making it through from the Internet to the domain, I tried from 2 different IP Addresses.
Probably a firewall issue.

I think I fixed the issue with it not connecting. Should I just allow Port 80 for everything on the firewall? Currently looking to see where to save this cert to

Also here is a list of issued certificates crt.sh | nextcloud22.net

Testing and debugging are best done using the Staging Environment as the Rate Limits are much higher. Rate Limits are per week (rolling).
