Cloudron Forum

@nebulon Hi, the DNS records seem to match with what https://www.whatismyip.com/ it is, as well as the WAN IP on the router's settings, and I am also fairly certain that the Public IP that we have been given is static.

If I try to curl to <publicip>:80 or :443 within the terminal of the server itself it does not seem to respond, and responds with:

curl: (28) Failed to connect to <pulicip> port 80: Connection timed out

and

curl: (28) Failed to connect to <pulicip> port 443: Connection timed out

However, when curling to it on my windows laptop, I get a response of the HTML which displays the "You are seeing this page because the DNS record of <publicip> is set to this server's IP but Cloudron has no app configured for this domain." page. Which lines up to what I see when I actually put that into a web browser.

However when off the network (on mobile hotspot) on the laptop I get;

C:\Users\XXXXX>curl <publicip>)
curl: (28) Failed to connect to <publicip> port 80 after 21045 ms: Timed out

I'm quite new to this but I am trying to setup a cloudron server on a Ubuntu 20.04 server running at my home. When trying to access the server my.(domain) [details will be obscured for privacy sake] it loads and responds with a "(domain) took too long to respond" error. When connecting from the inside network it works perfectly fine and shows the dashboard.

I have also ran into an error that keeps cycling within the logs when trying to renew the certificate which is;

This error cycles for a couple of attempts before using fallbacks, which I haven't provided it with any. This may be the source of the problem but I am unsure.

The biggest question is why it would not respond to the outside, whether it's a port forwarding issue (though I have both 80 and 443 forwarded to my server's internal ip, or something else.

I have tried some fixes from other similar cases but they all seem to not fix or affect the problem in any way. If there are any other possible fixes available I am open to suggestions.

Thanks.
