Having same issue, plugin worked perfectly fine on my dedicated server where I have root, but once the website with this plugin ended up on my shared Bluehost environment, it didn't work anymore.
I set the query.port to 25570, and checked if it was open (it was) but the website doesn't seem to connect/reach the game server (does it try to connect through a random port when trying to query the port on another server?)
edit:
Wow I just wasted
2 HOURS finding out what the problem was (while actually not even having a single error pointing me in the right direction)
Your folder at /library/EWRporta/block actually had to be /library/EWRporta/Block
On Bluehost capitalization matters a lot, and thus the cronjob never found the ServerStatus.php file to begin with (and never printed an error).
If you install XenPorta, that addons creates the /Block/ folder, so might I suggest that in an upcoming update you rename the /block/ folder to /Blocl/ to avoid issues with other hosts that have the same strict naming policy as mine?
