I’ve set up janus behind nginx proxy and also serve jangouts from that nginx. Trial with 2 clients seem to bring them to the room, but neither video nor chat seem to work. Most likely I need advice about the configuration (both janus.jcfg and videoroom).
EDIT: I connect A from chromium and B from an Android handset. A can see B and gets chats from B, but B cannot see A nor get chats from A.
Maybe a chromium issue?
Use the Admin API to debug connectivity issues:
Thanks!
I used chrome://webrtc-internals to investigate the chromium browser, and it showed me that jangouts have compiled in stun.l.google.com as stun server. I needed to patch that in its js file, and then get my chromium to discard any cached js for the site (which wasn’t easy)… but eventually I got it up. Now using my own coturn for stun service, and I’m a “happy camper” 
Thanks again.
