Hi , thanks for instant answer.. 

Yes it same IP address and network.. 

and the ports , 80, 443 and 3389 its open in router firewall.

Pls, close 3389 immediately! It is a very bad idea to open RDP traffic to the internet and you don't need that on your server as you can use RDP Gateway. I am wondering if this is also a TLS 1.2 issue. Pls, read Ask a question > Cannot configure remote web access on Server 2016

I have try that 

New-ItemProperty -Path "HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v2.0.50727" -Name "SystemDefaultTlsVersions" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v2.0.50727" -Name "SchUseStrongCrypto" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319" -Name "SystemDefaultTlsVersions" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319" -Name "SchUseStrongCrypto" -Value 1 -PropertyType DWORD -Force

New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\.NETFramework\v2.0.50727" -Name "SystemDefaultTlsVersions" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\.NETFramework\v2.0.50727" -Name "SchUseStrongCrypto" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\.NETFramework\v4.0.30319" -Name "SystemDefaultTlsVersions" -Value 1 -PropertyType DWORD -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\.NETFramework\v4.0.30319" -Name "SchUseStrongCrypto" -Value 1 -PropertyType DWORD -Force

But It doesn't help .. 

Any other ideas ? 

Did you reboot server?

In addition to the above save the below to TLS12-Enable.reg and import that into your server and reboot

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

Hi 

The Powershell and rebooting my server help, yehhoooo :-)

"Pls, close 3389 immediately! It is a very bad idea to open RDP traffic to the internet and you don't need that on your server as you can use RDP Gateway."

How do you use RDP Gateway?  Thank you.

Connect the Access Anywhere portal like remote.domain.com. You will see a list with tiles that represent the computers you can connect to. Save such a RDP connector to to your desktop.

Yes, that is exactly how I was doing it.  But it's now not working.  Once I get it working I will try it again but with port 3389 not opened to see if works.  Thank you.
