I get below inner Exception:

Environment: .NetCF v.3.5, Windows CE.

Do you have some ideas what can be the problem?

Thanks to your stack traces, we were able to locate the issue to the processing of TLS ClientHello packet – the error occurs when the client sends a ClientHello packet whose list of supported TLS ciphers contains two occurrences of a single value. When out TLS server library encounters this packet, it fails to process the ClientHello correctly. This will be fixed in the next release.

Update: This has been fixed in version 2017 R6.2.
