This could have happened for a variety of reasons, which are explained below:

1. Bad connectivity: There could be Internet connectivity issues on either your end or the other user’s end of the connection. Double-check your Internet connection to make sure the issue is not on your end.
2. Chat declined: The other user clicked “Decline” on the chat invitation.
3. Chat invitation timed out: If the other user does not take action to click “Accept” on the chat invitation, the chat invitation will time out.
