I think i found a bug.

Two servers, lets call them client and forum.
Client server is hosting simple site, but it also have link to forum.
Forum server is hosting nodebb.

client nginx.conf

    }

}

Right now when user will go to site.client.com/forum, he will see nodebb, and everything would be alright, but ...

when i log in to forum, some weird url redirect happens and path not follow forum config. Let me explain with examples:

When i log in i get redirected to:

1. https://site.client.com/?loggedin=true and it should be https://site.client.com/forum/?loggedin=true
2. https://site.client.com/categories?loggedin=true and it should be https://site.client.com/forum/categories?loggedin=true
3. https://site.client.com/topic/1/welcome-to-your-nodebb?loggedin=true and it should be https://site.client.com/forum/topic/1/welcome-to-your-nodebb?loggedin=true

... so it just cuts out forum part. If i type forum to web browser like it should be, everything is fine, but not when logging in.

I think nodebb is responsible for this rewrite or i miss something in config?

Heres the browser console error when logging in:
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.

Hm i found stack trace JS in browser problem could be here but i could also be wrong

assets/src/client/login.js

success:function(e){ var n=utils.urlToLocation(e.next).pathname;
var r=utils.params({url:e.next});
r.loggedin=true;
var o=decodeURIComponent($.param(r));
window.location.href=n+"?"+o}

Reinstalled nodebb and still the same problem.

What is your url value configured in config.json? It should match exactly the url at which you access the forum, including the correct protocol and subfolder.

[MoJo]

Its "url": "https://site.client.com/forum/"

Checked again and now this nginx config is not working it must be something with nginx im testing it again.

After fighting with nginx i just removed parts from nginx that are not needed to just reproduce this weird login redirect behavior.

NodeBB nginx subfolder setup.

If i change /public/src/client/login.js to ...

success: function (data) {                                                   
    var pathname = utils.urlToLocation(data.next).pathname;                  
    var params = utils.params({ url: data.next });                           
    params.loggedin = true;                                                  
    var qs = decodeURIComponent($.param(params));                            
    window.location.href = pathname + 'forum/?' + qs;                        
},

nodebb build, nodebb upgrade, ... everything works as expected.

@MoJo Ah yeah it looks like you've run into this bug: https://github.com/NodeBB/NodeBB/issues/8515

You'll need to cherry-pick the referenced commit to fix it in your install.

joolswills created this issue in NodeBB/NodeBB
