Not working in subdir behind reverse proxy

[Huljo]

Rocket.Chat version: 0.42.0 / Manual CentOS install / NGINX

I can't run Rocket.chat in a subdir.
My ROOT_URL=https://domain.com/chat
When I attempt to load rocket chat from https://domain.com/chat I get this response : 'Unknown path".

When I set My ROOT_URL to "https://domain.com/" I just get a loading status forever, assets are all absolute URLed to '/'.

My Nginx config (rocket.chat is running at localhost:3000) :

    location /chat/ {
       proxy_pass          http://127.0.0.1:3000/;
    }

Seems pretty similar to #2646 and #4460 but none of the proposed solutions are working for me.

Tested on 0.43.0. Same problem.

There is one trick:
My nginx conf:

location / {
    if ($arg_meteor_css_resource = "true") {
        rewrite ^ /chat/$uri last;
    }
    if ($arg_meteor_js_resource = "true") {
        rewrite ^ /chat/$uri last;
    }

    location /sockjs {
        rewrite ^ /chat/$uri last;
    }
}

Thanks to @abernix from Meteor project (issue) for pointing out that if settings.CDN_PREFIX is defined, setBundledJsCssPrefix helper is used to rewrite urls and not bundledJsCssUrlRewriteHook, the default implementation. So subfolder can't be set before URLs during boilerplate template instantiation. I'm not using settings.CDN_PREFIX so I'm actually trying to remove it.

Has this problem already been solved?

[Huljo]

No, I actually set my path as a CDN_PREFIX to serve my assets.

[MaluNoPeleke]

Can you describe how you did that?

[Huljo]

Open mongo shell on your server and type (replace [...] by your values):

> use [ROCKETCHAT_DATABASE_NAME]
> db.rocketchat_settings.update({ "_id" : "CDN_PREFIX"}, {value: "/[SUBDIR_PATH]"})

This is not a fix, just a dirty way to access your app with the actual release on a subfolder, voice calls/file uploads still not working.

CDN_PREFIX is not supposed to be used to access to your subfolder but like I said above Rocketchat is using it by default (even when value is empty) instead of the meteor webapp default implementation that is properly adding the complete path before each URL using __meteor_runtime_config__.ROOT_URL_PATH_PREFIX.

Seems fixed on 0.46.0! Thanks
