Subject Re: guacamole 0.9.9 immediately disconnects all sessions

Hello again!

I just picked up this project recently and was delighted to find that a
restart of the VM I was testing it with fixed the issue! I guess I never
restarted the server in my earlier testing.

I'm disappointed because I work as a sysadmin and this should have been a
no-brainer. Apologies for the false alarm. I am really enjoying the program
and we will likely replace an old VPN server with this. Yay!

Thank you again for your willingness to help. :-)

 - Benjamin
