When I did the netstat for “:80 “ it returned nothing, same with 443
(had to make new account to continue conversation because I had some new member limit)

hahaha, new account, sneaky 🕵️♂️
I’d do a rebuild of the app:
```plaintext
cd /var/discourse
git pull
./launcher rebuild app
```

It says “Device docker0 does not exist cannot connect to docker daemon”

Here’s a good Topic on Docker install:

Try that?

I’d be skeptical it’s a broken install in case nothing is listening on 80 & 443.
I’d suggest start afresh instead of diagnosing because your forum isn’t launched yet, Just reformat that server and follow the install guide properly.
Your DNS records are fine I’ve just confirmed that.

But Bhanu if you view source there is HTML and its a basic Ember skeleton … why would that be if its a firewall? Surely that would block it completely?

That’s being injected by your ISP or something because I’ve tried to access in browser (Unable to connect) and curl from my servers and response was (connection refused) so it’s definitely something specific to you I guess.
Ps: if you see from inside his vps, nothing is listening on Ports 80 or 443 so it’s definitely your DNS trying to load some content. what DNS do you use?

Interesting idea … by why include an Ember header? It’s a blank page too, not even a helpful message 🙂
