Can't open the URL suggest at the end of install - VirtualBox VM

[d43m0n1k_sek]

Tried on Ubuntu Server and Kubuntu Desktop (both 22.04) - same error on all after this:

                        WELCOME TO CLOUDRON
                        -------------------

Visit one of the following URLs on your browser and accept the self-signed certificate to finish setup.
  * https://<ipaddr>

On server I can't open the url without a browser, tried firefox (didn't work), and elinks (same error) 

On firefox desktop I get "Unable to connect

An error occurred during a connection to <ipaddr>

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web." 

I can spin up another server instance and rerun and grab logs, but all of that goes with no error. I just can't get the "self signed certificate" like I'm supposed to. 

And if I take the "https://" off the ipaddr, it tries to log me into my router login (but external facing? Login doesn't work)

So, I'm confused. 

Please help....

For a start only Ubuntu Server is supported. If you see your routers login, can you make sure you have portforwarded all required ports (for a start 80 and 443) to your server in your routers settings?

Hello I wanted to apologize for the lack of response, as right after I posted this had a family emergency and the holidays and it completely vanished from my mind.

I want to confirm that Port Forwarding was the kicker, as I was following a Doc for Guacamole install instead of Cloudron's full doc for the base install, there were no instructions in the Guac doc to do port forwarding.

Thank you so much!
