The proxy is waiting for a new session - Windows 2012 R2

[Benoit_C]

Qlik Sense Enterprise on Windows is installed on a Windows 2012 R2 server.

Accessing the Hub leads to:

An error occurred
The proxy is waiting for a new session. 

Environment

• Qlik Sense Enterprise on Windows 

Resolution

Verify if PKCS is disabled.

If PKCS is disabled, it will need to be enabled and the Windows host restarted.

Example using IISCrypto:

Cause

Some required cipher suits for TLS 1.2 are not available on Windows Server 2012 R2.

For more information (Windows 2012 R2 and Windows 8.1) see https://docs.microsoft.com/en-us/windows/win32/secauthn/tls-cipher-suites-in-windows-8-1 

The most common used TLS Ciphers are:

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 

These are not available on 2012R2 and, unfortunately, cannot be added.

Any customer that wants to keep their current schannel configuration would need to move to Windows Server 2016\19.
