Dynmap multi-server returning invalid json

[tillerrr]

Followed both guides correctly, can see the Dynmap through LiveAtlas on a non multi-server configuration, when enabling the multi configuration, it states it returned invalid json. Dynmap version is 3.7 beta 4.

I currently have Dynmap directed to a mounted NAS drive, and also mounted the same folder on the drive to the LXC running nginx with LiveAtlas, with a soft symbolic link within the same folder as index.html. I can access the .php files fine through URL

LiveAtlas configuration:

window.liveAtlasConfig = {
            // To configure multiple servers, see https://github.com/JLyne/LiveAtlas/wiki/Configuring-Multiple-Servers.
            // Example multiple Dynmap servers on external webserver configuration
             servers: {
               lobby: {
                 label: 'Lobby',
                 dynmap: {
                     configuration: 'Dynmap/lobby/web/standalone/MySQL_configuration.php',
                     update: 'Dynmap/lobby/web/standalone/MySQL_update.php?world={world}&ts={timestamp}',
                     sendmessage: 'Dynmap/lobby/web/standalone/MySQL_sendmessage.php',
                     login: 'Dynmap/lobby/web/standalone/MySQL_login.php',
                     register: 'Dynmap/lobby/web/standalone/MySQL_register.php',
                     tiles: 'Dynmap/lobby/web/standalone/MySQL_tiles.php?tile=',
                     markers: 'Dynmap/lobby/web/standalone/MySQL_markers.php?marker='
                 }
               },
               smp: {
                 label: 'SMP',
                 dynmap: {
                     configuration: 'Dynmap/smp/web/standalone/MySQL_configuration.php',
                     update: 'Dynmap/smp/web/standalone/MySQL_update.php?world={world}&ts={timestamp}',
                     sendmessage: 'Dynmap/smp/web/standalone/MySQL_sendmessage.php',
                     login: 'Dynmap/smp/web/standalone/MySQL_login.php',
                     register: 'Dynmap/smp/web/standalone/MySQL_register.php',
                     tiles: 'Dynmap/smp/web/standalone/MySQL_tiles.php?tile=',
                     markers: 'Dynmap/smp/web/standalone/MySQL_markers.php?marker='
			     }
               },
             },

Yes, MySQL. It is also working correctly according to the database becoming populated after run, as well as console output that it has connected to the database.

# The path where the tile-files are placed.
tilespath: /data/Dynmap/lobby/tiles

# The path where the web-files are located.
webpath: /data/Dynmap/lobby/web

# Disables Webserver portion of Dynmap (Advanced users only)
disable-webserver: true

*Note, the Dynmap is on a separate LXC than LiveAtlas, thus the mount location is different. The mount is located under /data/. The LiveAtlas LXC is also mounted in the same location, however, a symbolic link is used rather than bind mounting into the nginx folder. Still access's the files fine, no 404's all return 200's.
