ERROR: ssl error occurred (system call failure)

[Brent]

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?

[Brent]

I had OpenSSL 1.0.1f on the server and OpenSSL 1.0.2g on the client.

I updated the server to OpenSSL 1.0.2 and everything appears to be working fine now.

Thank you.

If anyone else needs to update OpenSSL on an Ubuntu OS, I found this link helpful:

Great! Just what I expected it to be.  Thanks for the update on this @Brent.

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?

i have the same problem from Windows 10 to MacOS Sierra 10.12.6.

there stands OpenSSL 1.0.2 22 Jan 2015
