error manually executing sentinel

[SherabPereira]

Hi, following the guide Desire provides on its website and after getting the Watchdog expired status I had entered the following commands on the remote console:

cd ~;

cd ~/.desirecore;
./sentinel-lin64

after entering that I receive this error:

Using desire.conf: /root/.desirecore/desire.conf
2017-12-27 06:03 Running sentinel
Error: Invalid IPv6 URL
2017-12-27 06:04 Running sentinel

Could you give me some advice of how to sort this out please?

many thanks.
