Hi Nick,
You are absolutely correct, guacd didn’t automatically started when I rebooted
the server.
So the below error is resolved with guacd service start, but now it is throwing
below error:
12:05:30.646 [http-nio-8080-exec-9] DEBUG o.a.g.net.InetGuacamoleSocket -

Thanks for the prompt response guys.
I resolved the permission denied issue, the issue was json extension was not
properly installed. I reinstalled the extension and now I can generate the
token using curl command.
But when I use that token in the browser connection fails with below error in
the Tomcat:

Please suggest.
Is guacd running and accessible?
