Hi all, I have installed Nodebb v1.14.x and setup http://forum.example.com in config json and setup reverse proxy for nginx but I still can not open the forum with http://forum.example.com url. Only http://127.0.0.1:4567 is opened but with message "Looks like no connection to db".
Can someone say what did I do wrong here?
My configs are below:
config.json
{
"url": "http://forum.example.com",
"secret": "secret",
"database": "mongo",
"port": 4567,
"mongo": {
"host": "127.0.0.1",
"port": "27017",
"username": "nodebb",
"password": "password",
"database": "nodebb",
"uri": ""
}
}
/etc/nginx/conf.d/nodebb.conf
server {
listen 80;
server_name forum.example.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:4567;

@Evg-R Welcome to NodeBB 
I am not noting anything awry config side and suspect your nodebb instance is unable to connect to your mongodb.
[[email protected]]/opt/nodebb% netstat -na | grep -i listen| grep 27017
tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN

[[email protected]]~% netstat -na | grep 4567

If so, have you confirmed that you are able to connect to mongod via cli as your nodebb user?
If so... try launching nodebb w/the --log flag, e.g.:
./nodebb -l start
Watch the messages that scroll by, eh? Then recheck what's happening on port 27017, should be something like:
[[email protected]]/opt/nodebb% netstat -na | grep 27017

Good luck and have fun! 
Hi @gotwf

While testing, I'd mind to 0.0.0.0 and confirm that connecting directly to the port produces a healthy page. You can close it after you are done troubleshooting.
Currently if I open http://0.0.0.0:4567/ I see home page but then message appears:
Looks like your connection to NodeBB was lost, please wait while we try to reconnect.
if I open http://0.0.0.0 I see
Welcome to nginx!
http://forum.example.com/ is still can not be opened

You need to bind to 0.0.0.0, but not browse to it. That's not its address.
If that doesn't fix the connection issue, then we have a problem.

That's expected. You can't use 0.0.0.0 like that ever. And you can't use any IP address for this situation unless your default goes here, and it doesn't in your config, so that will never work.
Ok, what else should I check or setup to see NodeBB opened with http://forum.example.com in the browser? I can post any info to get help to solve this issue

We're still trying to check the basics. Test http://yourip:4567/ and see if it is working correctly.
@scottalanmiller under "yourip" you mean IP address of the my linux ubuntu vm? It's dynamic ip, NAT shared from my laptop. I can not open NobeBB with http://myip:4567/ also

It has to be accessible from somewhere, or the Nginx can't reach it, either.
But we know it is reachable from somewhere, because you got an error from it. So use its IP from wherever that was.
@scottalanmiller And how to make it accessible for Nginx?
@scottalanmiller sorry I tried again and I could open http://myip:4567 but got the same message as for localhost:
Looks like your connection to NodeBB was lost, please wait while we try to reconnect.
You may not have port forwarding set up at your router so you can access it through the internet.
Do you have another computer on your local network? You may be able to check if you can access it through your LAN.

Ah, that will do it then. That's got to be solid and working before the proxy will work.
@Evg-R said in Can't open Nodebb with URL from config.json:
@PitaJ Yes I haven't set up port forwarding for router. Could you specify which ports and ip to specify for forwarding ports?
It's the port you specified... 4567, and your IP address. The one that you just used to access it.
@scottalanmiller I have added forwarding port 4567 to router for ubuntu vm 192.168.1.4 TCP+UDP 4567 but I have still the same issues...

That's not necessary. You were already testing from your LAN. Let's stay focused on testing one thing at a time. We don't want to jump around and get confused. (And now that we know your IP we can be explicit as to what we mean.)
If you add a hosts entry for your 192.168.1.4 to your forum.example.com and you browse to http://forum.example.com:4567/ does the issue clear up?
