@itsbhanusharma Thanks, for replying. Gonna try it asap. Keeping this updated @pfaffman - no, only Discourse SOLUTION [image] Add an offline page to display when Discourse is rebuilding or starting up Sysadmins warning This guide is intended for advanced users, who are already using nginx outside the docker container. By following this guide you make your setup more complicated and will lose some speed benefits like HTTP2 if you’re not running Ubuntu 16.04 or later. Proceed with caution! When Discourse is rebuilding or starting up, your users will usually either see an error message from their browser… [image] …or a not-so-nice 502 error message from Nginx: [image] If you’re a perfectionist … @itsbhanusharma, @pfaffman - thanks both for help and your time. Highly appreciate it! Also, special thanks to @fefrei Cheers! :slight_smile:

That is the problem.. there is no service running there. And it should be running right? – By the configuration. That problem appears when i install nginx. And letsencrypt. Before doing that, i could reach my discourse on that port. EDITED: [image] dbm: seems like docker-proxy is not being loaded and not forwarding to port 25654 - Also i had a problem that was saying that port 80 was being used. And after that i’ve rebooted, and ngnix didnt say that we have some errors. dbm@hkh:~$ sudo nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful Any advices or tips what could i do to sort this out! Thanks in advance Like i said here, i think that problem come from here.

Do you have other web sites hosted on this server? What are you trying to do?

Docker isn’t running because Your nginx has occupied Port 443 for SSL! You need to use websockets instead of proxy redirect. Take some cues from Here: Add an offline page to display when Discourse is rebuilding or starting up

What are You trying to achieve?

That configuration looks okay but is there a service running on

http://hkh.pm:25654/

Because that is not returning anything
