Use Yajsml to combine files.

Minify only constructs individual files and optionally compresses them with UglifyJS.

[cweider]

Should be fixed by af4bd5c, could you check?

[cweider]

Also, thanks for the good error report.

[mmehnert]

No. not really. Still the same error.

[mmehnert]

Confirmed. This is fixed. Thanks for the great support and all the work! :-)

[mmehnert]

Could you please hit me or something like that? I don't know what I did when I tested last time to get the idea that everything is fine. Pull Request #521 did not fix this. :-( I still get the same error with d868fd7 and 6fd73ec :-(
Everything works fine in b661ef5

[mmehnert]

With this merged into current master I still get the same error. :-(
Would it help if I send you a virtual machine with nginx configured for testing?

[cweider]

@mmehnert, possibly, but at least some HTTP data. Requests are made to nginx, requests made to the etherpad instance (from nginx), and their responses will help diagnose this issue. It must be something with redirects, but, without more data, I couldn’t say exactly what.

[mmehnert]

Do you prefer Vmware or Virtualbox?

[cweider]

@mmehnert, oh, just the config should be good enough. That said, it would also be helpful if you could create a minimal configuration the reproduces the error. In my tests, this works.

[mmehnert]

Found something. It works fine in standard configuration. The Problem appears as soon as I set httpAuth in settings.json. That somehow messes up everything.
Used a minimal configuration otherwise:

server {
        listen       443 ssl;
        server_name  pad.mydomain.org;
        access_log  /var/log/nginx/etherpad.access.log;
        error_log   /var/log/nginx/etherpad.error.log;

        ssl                  on; 
        ssl_session_timeout  5m; 

        location / { 
            proxy_pass             http://localhost:9001;
            proxy_buffering off;
        }   

}   
server {
    listen      80; 
    server_name pad.mydomain.org;
    rewrite     ^(.*)   https://$server_name$1 permanent;
}  

[cweider]

Ah, ok, then the fix should be pretty straight forward, I don’t see any reason for static assets to require authentication. Master is in limbo right now, but just move the block at server.js:127 beneath the static assets and that should fix it..

[mmehnert]

Hmm. I moved it to line 152 but somehow I could see content of pads without entering the password then. (restarted the browser but login was not requested.)

[jubro]

the same error occurs to me and I had no http auth activated.

But I used the specific IP of the etherpad host in my network and not the loopback. So with 0.0.0.0 everything works fine to me.

[n3storm]

same here as jubro explains.

Just in case: Debian Wheezy

[marcelklehr]

status?

[mmehnert]

still the same in

[mmehnert]

I mean, its possible to use nginx for authentication - then it's all fine. But the etherpad-lite authentication does not work through nginx.

[mmehnert]

But it appears to work in the current development branch. 916e52a
