activecollab 5 nginx url rewrite not working

Question

I was trying to install Activecollab as per the instructions here.

My vhost config for nginx is here

server {
    listen *:80;
    server_name collab.example.com;
    access_log /var/log/nginx/ac.access.log;
    error_log /var/log/nginx/ac.error.log;

    set $root_path /usr/share/nginx/html/collabs/public;
    root $root_path;

    index index.html index.htm index.php router.php;
    charset utf-8;

    if (!-e $request_filename) {
        rewrite ^/assets/(.*)$ /assets/$1 last;
        rewrite ^/avatars/(.*)$ /avatars/$1 last;
        rewrite ^/wallpapers/(.*)$ /wallpapers/$1 last;
        rewrite ^/verify-existence$ /verify.php last;
        rewrite ^/proxy.php$ /proxy.php last;
        rewrite ^/api/v([0-9]*)/(.*)$ /api.php?path_info=$2&api_version=$1 last;
        rewrite ^$ /router.php last;
        rewrite ^(.*) /router.php?path_info=$1 last;
    }


    location ~ ^/(assets|avatars|wallpapers)/ {
        root $root_path;
    }

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }


    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_read_timeout 150;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
    }

}

Output of nginx -V

I am getting error

Error — URL rewriting is not enabled. Invalid URL rewrite check response:

Any help is appreciated.

As discussed over chat and teamviewer debug session. There is a flag REDIRECT_CHECK in config.php for activecollab. You need to disable this redirection by defining this name in config

define('REDIRECT_CHECK',false);

Also you should change below part of nginx config from

if (!-e $request_filename) {
    rewrite ^/assets/(.*)$ /assets/$1 last;
    rewrite ^/avatars/(.*)$ /avatars/$1 last;
    rewrite ^/wallpapers/(.*)$ /wallpapers/$1 last;
    rewrite ^/verify-existence$ /verify.php last;
    rewrite ^/proxy.php$ /proxy.php last;
    rewrite ^/api/v([0-9]*)/(.*)$ /api.php?path_info=$2&api_version=$1 last;
    rewrite ^$ /router.php last;
    rewrite ^(.*) /router.php?path_info=$1 last;
}

to

location / { 
  if (!-e $request_filename) { 
     rewrite ^/assets/(.*)$ /assets/$1 last; 
     rewrite ^/avatars/(.*)$ /avatars/$1 last; 
     rewrite ^/wallpapers/(.*)$ /wallpapers/$1 last; 
     rewrite ^/verify-existence$ /verify.php last; 
     rewrite ^/proxy.php$ /proxy.php last; 
     rewrite ^/api/v([0-9]*)/(.*)$ /api.php?path_info=$2&api_version=$1 last; 
     rewrite ^$ /router.php last; 
     rewrite ^(.*) /router.php?path_info=$1 last; 
   } 
   try_files $uri $uri/ /router.php?path_info=$uri&$args; 
}

With the help of Tarun I managed to resolve this. What we did is

1. Confirmed that this has nothing to do with nginx and rules
2. Disabled the REDIRECT_CHECK in configuration files.

Now it seems to be working fine.
