SignalK gone after upgrading to v3.60~39

v3.60~39
Cannot access SignalK
Reboot does not help

Hi, on our systems, SignalK works fine on v3.60~39.

Can you login and look in more detail?

Downgraded to v3.54 all ok
Back to v3.60~39 and SignalK server page does not work

The same on 3.60.46

I just performed the 3.50 to 3.60 update yesterday and the signalk web portal was not longer accessible via IP, local DNS, nor the VRM tunnel. It seemed that some of my signalk plugins were still functioning (N2K gateway for my nav apps), but others were not. Booting back into 3.55 resolved the issue.
