ERROR: ssl error occurred (system call failure)

Recommended Posts

I get the synergy system to work great without ssl encryption, but when I turn on encryption I get a system call failure which also causes the cursor to get jumpy.

The ssl option is turned on for both client and server.


Is this a bug or is there some other setting I need to change?

Thank you.

Below is the log error:

What Synergy version do you have running on each of your machine? Also, what version of OpenSSL do you have on each of them?

I'm seeing the same error using macOS 10.13 on server and Windows 10 on client.  I have no idea what version of SSL the Windows client is using.  Any tips on debugging this?
