OpenHAB connection failed

I use IOS system
I have put the following information
local URL : https://192.168.0.150
Remote URL : https://myopenhab.org

but unable to connect to the sitemap page Error Response status code was unacceptable: 404.

I don’t use iOS but don’t you need to also define the port somewhere on the local URL? https://192.168.0.150:8443 perhaps? Also, in the Android app there is a flag to set to allow it to accept the self signed certificate you will get from the local HTTPS connection.
