readTLS: (unknown error code) (49)
Hi everyone:
I connected a VM(CentOS7) with vnc through guacamole。It's always black and reconnected every once in a while。

version 1.0 ?
Is there any better way to view version information of libvncclient?

What about the version of libvncclient in use on the system running guacd?

I changed the code with this 'https://github.com/apache/guacamole-server/pull/217/files'(guacamole-414), and restart the guacamole docker.
But frequent TLS errors and consequently disconnections still exist.
Is there any missing operation steps?

A couple of possible things...
- What VNC server are you using? It's possible that it is using an incompatible VNC (RFB) protocol to try to communicate with the client, something that Guacamole doesn't support.
- If you're running CentOS 7 you may be hitting this bug: https://issues.apache.org/jira/browse/GUACAMOLE-414. It requires a certain version of libvncclient for the fix to work, and I don't think CentOS7 includes that version, so you may have to build/update it manually.
