If your CDN uses the Akamai network, an upgrade to improve security on the Akamai service may break your stream.

"This had an unintended consequence of mandating the RTMP STREAM URL end in EntryPoint. This will only impact those who setup their live channel using OTHER RTMP ENCODER. For those impacted please change the "Entrypoint" at the end of the STREAM URL to EntryPoint or simply recopy the details from ENCODER SETUP into the encoder.
For example:
rtmp://p.epXXXXXX.i.akamaientrypoint.net/Entrypoint
Would need to change to end in EntryPoint:
rtmp://p.epXXXXXX.i.akamaientrypoint.net/EntryPoint

Those impacted include Teradek VidiU users, TriCaster users, OBS users, XSplit users, BroadcastMe app users, Teradek Cube users and more.

Those using the XML (Adobe Flash Media Live Encoder), APIs, Wirecast (unless multi-bitrate) or vMix (CDN Presets only) are not impacted. Those using video files only, with no live channels, are also not impacted."
