help with TLS on 2016 version

#Security #SSL #Caché

Hi,

I am trying to connect to another server using  %Net.HttpRequest.

I keep getting this error  : SSL23_GET_SERVER_HELLO:unsupported protocol.

My guess is that the site I am reaching for uses TLS1.3 which is not supported in 2016, But I cant right now ask my client to upgrade.

Is it possible to override this ? install some kind of a patch or a more recent version of openssl on the server ?

Thanks

Amiram

As a short term approach, you may want to look into using Stunnel in client mode to encrypt the traffic and then set something up similar to:

This would mean that the traffic between your 2016 instance and stunnel is unencrypted but all on the same machine, and then stunnel handles the encryption between your machine and the external site using TLS1.3.

However, even if you go this route, I would still recommend getting the process started for upgrading to a newer version.
