Here are the reasons you may not be able to go live on Instagram:
If an account is new or has violated rules, it might not be able to use all the live features.
Version of the App: Updating Instagram often will make it possible for you to use live streaming.
Bad internet connection or technical difficulties with your device might stop you from broadcasting.
There are times when Instagram releases live features gradually to selected regions.
To broadcast live, you need to be at least 13 years old (in some places, it’s even older).
