iOS14.5 local network intermittent issues

We are getting intermittent network connectivity issues when connected to local network via zscalar VPN. Issues are happening only with iOS 14.5 and above versions. Is there anything required that were not required in iOS 14.4 and below versions to make network calls to APIs? 

Below are the app logs we see every time we get the network connectivity error:

Connection 63: unable to determine interface type without an established connection

Connection 63: unable to determine fallback status without a connection.
