Interesting... I have been trying to figure out why only one of my three Windows 10 PC's (all running same OS build, identical verstions of Chrome, hard reload'ed, etc.) would always fail to load the dashboard from my local Rpi; I was able to use the cloud dashboard on all of them however. Your fix jogged my memory of a problem I ran into some time ago, with a similar but not identical fix that @jp0550 provided: Patched webCoRE for Hubitat (2018/09/09)
I guess this fix never made it into the current repo.
I re-applied the above fix and now my problematic PC works fine with my local dashboard. I also noticed that this PC runs Win10 Home Edition while the other two (which didn't need this fix) are Win10 Pro; only difference in the Windows platform I can see.
