TLS 1.3 on Windows Server 2019

Hello,

 

I tried to enable TLS 1.3 on Windows Server 2019(IIS 10),

for some reason this doesn't work well.

In oposite of Windows server 2016 there are some changes.
I changed the registry settings to change this

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

if I do this on Windows Server 2016 nothing happens and everything keeps working.
on a windows 2019 server I get "Secure Connection Failed" on Firefox and "ERR_SSL_VERSION_INTERFERENCE" in chrome,
on internet they say the solution is to disable TLS 1.3
but I'm wondering if it's possible to leave it enabled and get it to work.

 

With kind Regards

Bart
