Cannot connect to Secure 11.26 web app running on Amazon server

[Richard I]

Hi,


I have downloaded a NT 11.26 app and included all the files I believe I need.....
and successfully downloaded the certificate
I have copied in libssl 1_1 and libcryto 1-1 CARoot.pem  and dh2048.pem vcruntime140.dll msvcr120.dll etc

On running from its sub domain address, to a secure port, absolutely nothing happens in the logging window or on the browser
If I run from the IP address of the server , I get some activity and the error message..
but I can log in successfully if I delete the secure port , rename the certificate folder  and use an insecure port

The error message I get is -

This site can’t provide a secure connection54.197.66.57 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.


as always, help appreciated, as Im out of my league here.....

Cheers
Richard

It sounds to me like either

a) the Visual Studio 2017 runtime is not installed on the server, or
b) The server program has not been added to the Windows Firewall on the server machine or
c) There is not an appropriate AWS security Group set opening port 443 or
d) In your WebServer procedure, NetTalk extension, the host name is not set to SET:DOMAINS

Cheers

many thanks Bruce,

The issue was the Visual Studio Runtime missing on the Amazon server
Successful  with Downloading  and installing   vc_redist.x86.exe
