Looks like your connection to NodeBB was lost, please wait while we try to reconnect.

I was reading for several hours for solution through NodeBB's official forum and searching through google for answers.

I just freshly installed NodeBB v1.15.3 and now I am having issues. When I open the site it shows it without any css and has error

"Looks like your connection to NodeBB was lost, please wait while we try to reconnect."

at the bottom of the site.

From logs I saw this:

So it has 2 errors, what I understand: [cache-buster] and [socket.io]

My config is currently this:

{
    "url": "https://foorumi.vankilapalvelin.com",
    "secret": "***",
    "database": "postgres",
    "port": 80,
    "socket.io": {
        "origins": "https://foorumi.vankilapalvelin.com:* http://foorumi.vankilapalvelin.com:* https://www.foorumi.vankilapalvelin.com:* http://www.foorumi.vankilapalvelin.com:*"
    },
    "postgres": {
        "host": "127.0.0.1",
        "port": "5432",
        "username": "***",
        "password": "***",
        "database": "***",
        "ssl": "false"
    }
}

If one of you Gurus could help me with this because I am starting to lose hope with it. I think the biggest problem is with the socket.io but not sure what is wrong with it.

Could you please tell us which guide (documentation) you've followed during NodeBB install process?

Your server reposponds Error 503 (Service Unavailable) from time to time.

NodeBB Community (community.nodebb.org)

Are you using a reverse proxy? As this error says, you should be:

Using ports 80 and 443 is not recommend; use a proxy instead.

As for this:

"origins": "https://foorumi.vankilapalvelin.com:* http://foorumi.vankilapalvelin.com:* https://www.foorumi.vankilapalvelin.com:* http://www.foorumi.vankilapalvelin.com:*"

It's strongly recommended to only have a single URL for NodeBB. Also, having a www. when your forum is already on a subdomain is not recommended. Also, you shouldn't run your site on both http and https as it can put your users at risk.

I can get same result when changing default theme on the cloud hosting. Due to upload handling and dropping them after some time. Nothing wrong with NodeBB here.

Please try Redis or MongoDB instead of PostgreSQL. A better choice for most users.

Tested it again on a freshly installed server. Please wait while we try to reconnect shows when NodeBB is installed by a root user and not a normal user.

Solution: add new non-privileged system user and do not use root to install NodeBB. Such note should be included on every install guide.
