Version 5.2.1 Http Monitor not working

I just downloaded the open source version 5.2.1 and tried out the Http Monitor, but it is not working on either proxy or turnnel setting.  I tried same using the tcpmon it works.

I got 500 error when trying to reach the monitor, and don't see any request in the monitor:

HTTP ERROR 500
