Video streaming services from the IRIS Connect teaching website don't work when the user's device is behind a proxy both automatic and manually configured proxies:
The user is shown connection error messages. Opening all ports on the firewall does not resolve the problem.
Solution
Luckily, IRIS Connect are aware of this issue. They must enable tunnel streaming when behind a proxy for all associated school accounts. This utilizes the RTMPTE protocol which resolves the issue.
