Can not Connect via CDS Api to Server

[JoergG]

Hi @ All,

 

I have a problem to Connect a Netphone Server via CDS Api.

 

CDS Api 11.32

Server Netphone 11.52

Windows 2016R2

 

Connect from CDS API to Server via IpPbx Username/Password

Libmanager init:

libManager = new LibManager();
libManager.BaseProtocol = SProxyObject.BaseProtocol.TCP;
libManager.Username = "AdminUser";
libManager.Password = "AdminPw";
libManager.WSBaseUrl = "127.0.0.1";
libManager.AuthenticationMode = SProxyObject.AuthenticationMode.UsernamePassword;

 

Trace Output:

Can anyone help me ?

Hi @ All,

 

After a lot of googling and testing on a laboratory server,
maybe I found the cause.

 

After I disabled TLS1.0 (server) in the registry, the problem occurred.

 

RegKey:

HKLM\SYSTEM\CurrentControlset\Control\SecurityProviders\SCHANNEL\Protokols\TLS 1.0\Server

DisabledByDefault: DWORD=1

Enabled: DWORD=0

 

Original problem:

Registration on a Netphone Client / SwyxIt with user / password works.

The same user / password combination in the application (CDS-API) writes the above error.

 

After activating TLS 1.0 (server) the registration works.

 

best regarts

Jörg
