Just a brief question I hope someone can help....No answer on the forum similar question. Several of our connections to various public servers are failing and it appears that it is related to TLS V1.2. I have installed all of the latest updates via package manager and created a new project to test this without success.

ssl.h shows nothing for V1.2 however there is a forum answer from digi that states V1.2 is supported in NET-OS. Apple push notifications now require TLS 1.2 to connect along with NOAA weather servers.

Secure connection attempts return a -2 (SSL_UNSUPPORTED_CIPHER)

Is there some define I am missing or other issue I may have missed?
Package manager states that it is using OpenSSL V1.0.2.e which seems to reflect it has TLS 1.2.

Thanks for any help.....I've already spent 2 days troubleshooting this.....

This was answered via support case. Neots does include openssl 1.0.2e which does support TLS 1.2. There are 2 sample apps, openssl client and openssl server that demonstrate TLS 1.2 connectivity with openssl server/client on Linux side. SSH server that ships with Netos was not updated and does not support TLS 1.2.
