I can access my install on ubuntu and one on windows not.

I can access and https://ns1.hostingandlearn.net:10000 both on Ubuntu 16.04 desktop also I can access on windows but I am unable to access https://ns1.hostingandlearn.net:10000. I have added server domain name hostingandlearn.net by enom even adding nameservers to webmin still is not showing up.

Your domain.net is not resolvable yet. At least not for me. So IP hasnt propagated yet? Not sure how Ubuntu was smart enough to resolve it but windows wont. All though I’m also on Ubuntu and it wont ping, resolve or dig any dns info. How long ago did you set the domain to point to an IP?
