Xenforo Xenforo Friendly Urls Stopped Working

Today for some reason my xenforo friendly urls stopped working. Here is my nginx config:

Code (Text):

location / {
     index index.php index.html index.htm;
     try_files $uri $uri/ /index.php?$uri&$args;
}

#location /admin.php {
    #auth_basic "Private";
    #auth_basic_user_file /usr/local/nginx/conf/htpasswd_admin_php;
        #include /usr/local/nginx/conf/php.conf;
        #allow ;
        #allow ;
        #deny all;
#}

location /install/data/ {
     internal;
}

location /install/templates/ {
     internal;
}

location /internal_data/ {
     internal;
}

location /library/ {
        internal;
}

# xenforo 2 uncomment / remove hash from next 3 lines
location /src/ {
     internal;
}

They were working yesterday but not today. They give a 404 not found error. I am at a loss as to why this happened. Any help would be much appreciated.

Thanks,
