just update -
this issue happened if you are installing Windows Admin Center 2019 on your Windows Server 2019 machine.
admin center was installed on my Server.
I removed the Admin Center before the installation of skype.
but this not fixes the issue.
because some who port 443 still used.
I previously had Windows Admin Center installed, and now nothing else can use the same TCP/IP port
Manually run these two commands in an elevated command prompt:
netsh http delete sslcert ipport=0.0.0.0:443
netsh http delete urlacl url=https://+:443/
netsh http delete urlacl url=https://+:443/
and please don't forget to run - IISreset after you running those commands.
or
when you install the Admin Center if you going to install skype on this machine.
please change the port when you install the Admin Center.
Microsoft adds this note lately -
more details -
If you are installing Windows Admin Center 2019 on your Windows Server 2019 machine, it will prompt you for a port to listen on. There's a likelihood you might choose port 443, but if that machine has Skype for Business Server 2019 installed on it, or is going to have Skype for Business Server 2019 installed on it, then you must choose a different port number.
Why is this the case? If Windows Admin Center 2019 is running on port 443, you will not be able to connect to the server using the Skype for Business Control Panel, nor will you be able to connect to any internal web service running on the server (Address Book Web Service, Autodiscover Service, WebTicket Service, etc). In fact, you will not be able to connect to any Internal Web Service URL. Please choose a different port, in the event you need or want to put Windows Admin Center 2019 on a server with Skype for Business Server 2019.
