Microsoft announced some time ago that TLS 1.0 and 1.1 would be deprecated in GCCHigh. As of today, you can no longer connect to GCCHigh if your browser isn't configured for TLS 1.2. In fact, there are many problems when network connectivity is done between nodes that support multiple versions of TLS. It's recommended that we all fully embrace TLS 1.2 and turn 1.0 and 1.1 off completely.
Happy coding...
