Hi all, I’m using cloud9 in a classroom environment, with c9vnc to support graphical projects in C++. My students and I are running into a host of difficulties with c9vnc, particularly with connecting to c9vnc via the noVNC software. I’ve managed to troubleshoot some of the problems - but one nagging problem that seems intermittent and inexplicable is that an installation that was working stops working in a particular way: the noVNC window comes up, but we just get a moving …, the noVNC connect button never shows up. Oddly, I can get to a working noVNC if I a) switch to Firefox from Chrome or b) change the URL to point to vnc_lite.html instead of vnc.html. Some of my students are finding that these workarounds no longer work, though.
