> Nor am I able to refresh the webpage to type another key.  The session appears to be lost and a new one started.  If I type before the page fully loads, I am able to type as many keys as I like before the prompt appears.  I am also able to press enter after that as many times as I wish, but once I press any other character it doesn't display, and enter stops functioning.
> The SSH server itself appears to be functioning normally.  It is a vanilla system I've been using for a year to no issue, the ~/.bashrc file is default, the only line in ~/.bash_profile is "archey".
> Tailing all files within /var/log/tomcat8 also doesn't seem to be useful in the least - https://hastebin.com/osazijutel.hs
> Kinda at a loose end here, no idea how to even start debugging it (only been using it for a few minutes).  The installation was using the default method for "Debian and Ubuntu", using the package repository "guacamole/stable".
