Hello! I’ve recently decided to try to install Discourse. Upon getting everything in the folder on Ubuntu 20.4, I’m getting a “Port 443 isn’t accessible via hostname” error. Trying to connect internally and externally won’t work at all. I’ve done a LOT of searching around. I’ve removed proxies via…

Make sure cloudflare is dns only. Gray cloud. Orange cloud causes the issue you describe.

That was one of the first things I managed to do. Both domains I tried I set to DNS only and pinged to make sure it was only going through to the IP and not proxied through CF. [image]

pinging the domain name is sending a time out. [image] is the IP address correct ?

I’m suspecting a firewall issue here. Which hosting provider are you using for discourse? Is the server using UFW or an external firewall that’s blocking inbound connections?

That juat means ICMP is being dropped. It doesn’t necessarily mean theres a DNS issue, but does suggest a firewall of some form is being used. @awexx - are you trying to host this on a charter broadband connection? 98.0.0.0 - 98.255.255.255 is an old Charter IP range for their cable network. They s…

Yes, I am using a Charter Broadband connection. I’ve ironically enough had 0 issues trying to host anything else via this network, 443 and 80 have opened fine and operated fine outside of my network. This is hosted on a local server on Ubuntu 20.4. It’s set to use the host network. Checking my rou…

If you’re on the same network as the server then the loopback, connection would explain why you can ping it, and he can’t. Either way though, this doesn’t sound like a Discourse issue, so I’m not sure we can really help you. The setup guide calls for a cloud server because it’s a simple and straig…

I understand, I was planning on getting a cloud server anyway for Discourse and also placing my other resources elsewhere if this didn’t work. Thanks anyway :slight_smile:

请确保 Cloudflare 的 DNS 仅处于代理关闭状态（灰色云朵）。橙色云朵会导致您描述的问题。
