ERROR: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

What happened?

https://github.com/symless/synergy-core/issues/4642

client (win10 2.4.0 and previous version) can connect barrier (GUI) but not barriers (headless) 2.3.3

I found the above issue 4642 while google.

It works fine with barrier (GUI) but not barrier-headless. When trying with barrers (headless) the client log says

[2021-11-13T11:51:03] WARNING: failed to connect to server: Connection was refused [2021-11-13T11:51:04] NOTE: connecting to '192.168.31.55': 192.168.31.55:24800 [2021-11-13T11:51:04] INFO: OpenSSL 1.0.2l 25 May 2017 [2021-11-13T11:51:05] ERROR: ssl error occurred (generic failure) [2021-11-13T11:51:05] ERROR: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol [2021-11-13T11:51:05] ERROR: failed to connect secure socket
