Beta Pool wont add my servers

Hi,

I can’t add my ntp servers to the beta pool.
The beta finds my servers but when i hit " Yes, this is my server,add it!’
I get the following error;

500 - Server Error

Ouch! That didn’t work, our server hit a bad gear.

It works on the live pool (ntppool.org) pool.ntp.org: westridaz's pool servers
