The Windows system event log shows Schannel EventID 36871 errors.
TLS 1.2 Server settings were not updated correctly:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server] "DisabledByDefault"=0xffffffff "Enabled"=dword:00000001
For a script that enabled only TLS 1.2, see TLS and SSL Support in Qlik Sense: How to configure Qlik Sense and TLS.
Edit the Windows registry to enable TLS 1.2.
