Raised when the Server is unable to create a Room.
Possible Causes
A user attempted to connect to a Room which does not yet exist, and Ad-hoc Rooms are not enabled.
You may have chosen to enable Room features that are unsupported or not available to your account.
A server-side error has occurred.
Possible Solutions
Make sure Ad-hoc Rooms are enabled in the Video settings for your account in Twilio Console, or create the Room explicitly using the REST API before attempting to connect to it.
Choose a Room configuration supported by your account.
If the problem persists, try connecting to another region.
