Keeps disconnecting in less than a minute

I am developing an iOS app that uses SIRI's speech to text to send text to Heygen to the streaming Avatar and I noticed today that it keeps disconnecting me in less than a minute. I though my codes are buggy but when i tried the InterActiveAvatarDemo swiftUI sample app, it is the same. Anyone here experience the same? or is heygen's server a little buggy atm?
