I have installed Zerotier I've changed options web server on BI to the new new network adaptor and restarted it. I've installed Zerotier on my phone and downloaded app. Put the ip address I got from Zero Tier phyical address on the BI PC as Lan and the Zerotier Managed IP as WAN put in user password and name. I can access the webserver on the actual BI pc but not on my mobile.
