Oof. I just checked in Chrome where I have a 4-up view with Cam v4 × 2, Cam OG × 1, and Cam OG Telephoto × 1. Everything loaded pretty quickly except for the standard Cam OG, which gives a “Connecting…” message until it times out with “Web Connection Failed”.
I don’t know why this is happening, but I’ll try to keep an eye on it.
