Sorry for replying to an old thread, but I finally resolved the issue I was having and thought it might help someone if they ever run into it.
Ahead of trying to get 1.2.0 going on my test server (debian) I wiped out my tomcat8 configuration and started over with the default tomcat9 configuration from debian "buster". I modified the server.xml file per the Guacamole manual and had a working Guacamole on port 8080. I further followed the instructions for using nginx as a reverse proxy with websockets and was able to get everything going. I still am not sure what I did wrong originally, but I believe it was in the <Connector> definition in my tomcat8 server.xml file.
