NAV 2016 in Docker Container returns "Could not create SSL/TLS secure channel" on web request

Hi all,

We do our in-house development in local Docker containers. We have a shipping solution that communicates with Fedex web services.

Since the last update of the NAV2016 Docker image artifacts (approx Nov 1, 2021 - perhaps a week earlier), when running a Fedex web service request, we receive an error "Could not create SSL/TLS secure channel".

This error does NOT occur in our production database or any non-Docker test databases.

References to this error point to a problem with TLS1.2 not being in the default configuration.

The shipping solution formats the web request and then calls it through a DotNet component "System.Net.HttpWebRequest"

Any ideas?

Thanks
