I have an application that uses Flash player and it's trying to connect to the Flash Policy service in TLS 1.2 (port 843) .
On Win7 with Internet Explorer, Flash Player 25 works perfectly with TLS 1.2, but with Flash Player 26 it fails to connect.
With FireFox it is also not working.
On Chrome everything is fine (all versions of Flash Player).
Do you have any idea why this happens?
This lack of TLS1.2 support was supposed to have been fixed, as discussed in a similar thread last year.
It's hard to say without inspecting it under a debugger.
Do you have a link that demonstrates the problem?
