PBExact UCP

I get the following error when I try to access the UCP in PBXact
PBX Firmware:10.13.66-17

Unable to connect to the UCP Node Server because: ‘Error: xhr poll error’

you may try : fwconsole restart ucpnode
or refer this link: http://issues.freepbx.org/browse/FREEPBX-11186

fwconsole restart ucpnode
Running PBXact shutdown…

Running PBXact startup…

I then did a complete reboot of the system and am still getting the same error:
Unable to connect to the UCP Node Server because: ‘Error: xhr poll error’
