Hello.

I am using the .net (2.0) DLL (v9.2.1.0) for some years now and have zero problems. Our program connects with HTTPS to our servers through cloudflare and with the above version everything works OK.

I just tried the latest version (v9.5.0.48) without any changes in my code and the dll fails to do a proper handshake with cloudflare. The same code works OK with any https IP not passing through cloudflare. I tried playing with SslProtocol but changes nothing. I am using the paid version (always doing .UnlockComponent) if that matters. Can you make out something from the logs?

I get the same thing on v9.5.0.54 when making a request to my website secured with Comodo SSL.

I've run several tests on the SSL and all report that it is setup correctly.

Did you find a solution to this?
