I bought a lot of Nginx reverse proxy servers, but cf is too slow in my country, I set my main server nodebb to be accessible only via vpn network, and I think that’s fine if no one attacks the server!
@veronikya only accessible via VPN is very secure, and easily the best way to completely isolate the site from the rest of the Internet.
The downside of this is that your site isn’t publicly accessible without the VPN connection which would mean it falls under the umbrella of deep web. However, depending on the content, it may be what is required in order to keep sensitive information or topics secured.
Hello
just for test, I wanted to test that configuration in my dev instance :
https://community.nodebb.org/topic/7930/using-cloudflare-with-nodebb
But I have this error uninterruptedly :
And I don’t know why

Cloudflare config :
@DownPW Does this issue manifest itself in Incognito mode?
yes, it does
@DownPW You should simplify the nginx config - below a suggestion

@phenomlab done
@DownPW Also remove these lines and restart nginx
root /home/XXXXX/domains/socket.XXXX.fr/public_html;
index index.php index.htm index.html;
Same
I see this on start log nodebb
undefined phenomlab forked this topic on
There’s more of an issue here - try to change any CSS or JS in the ACP, and you’ll see that it does not save.
???
@DownPW Now working for me in Incognito. Can you check
@phenomlab said in NodeBB socket with CloudFlare:
There’s more of an issue here - try to change any CSS or JS in the ACP, and you’ll see that it does not save.
due to socket.io configuration in nodebb config.json file
Actually I have delete socket.io block and change CSS and save is good.
@DownPW Ok, but that now means you should not need the socket A record anymore because it’s not used. From the logs, the socket is running on the site’s URL.
normal that it is not used (A record) @phenomlab because there currently, I do not use it because the socket.io block is removed from config.json.
I’m just in normal mode with Cloudflare :
I can put it back if you want ?
@DownPW It seems to be working fine without it, so I’d leave it. I see zero socket errors, so all good.
because I’m alone on the server.
The goal is to try to market this method before putting it into production where i have a lot of errors
And we can see that it doesn’t work when I try to reroute the web sockets in non-proxied mode. (socket error, no save when chnage in ACP, etc…)
I don’t know if I can make myself understood. @phenomlab 
@DownPW Understood. Even with just the two of us connected, I was still getting the websocket error, but I think that was related to config etc. In all honesty, this is yet another reason why I stopped using CF. I know you need it to hide your IP address, but if you bypass CF for the socket, you are exposing your IP anyway.
I know, I know,
too bad… I just wanted to test this method but it seems more complex than it looks to make it work correctly
The reverse proxy method is currently too expensive for me and technically too abstract
