Thank you all.
@Sebastien - I was trying to connect to the administration interface. http://hubitat.local works. Based on comments below I will use that as a second option, and first try the IP address assigned to the Hubitat. But it is good to know about http://hubitat.local because that is easier to remember if I don't remember the IP...
@jtp10181 - Thank you for the clarification! I will try a reboot also. Probably just good for it every once in awhile.
@rlithgow1 - re your step 1 of:
"Set a DHCP reservation on your server so no matter what, when your hub boots it gets the same ip address."
I don't have a server. However, my router is set up with "Manual MAC and IP Address Binding." I understood this will ensure the Hubitat always gets the same IP address.
I will use the ip address to access the hub.
@bobbyD - you are correct, the browser is trying to go to https. Each time I change it to http:// it goes back to https://. Does not matter because I'm going to use the above info and get to the hub via IP address.
