CData Connect AI

I’m facing a timeout error when executing queries to tables for a given connection in Connect AI. The error message is as follows: [ERROR] Execution of the SELECT query failed. Error: Timeout when wait response.I tried to increase the Timeout value in the connection Advanced Settings tab, but nothing changed. What should I do? 

I can't find the verification email to verify my Connect AI account. It's not in my inbox, or in the Spam or Trash folders. How can I verify my account?

I am trying to query my sources in CData Connect AI but they are running slow. They used to run instantly.What can I do to return to the speed the queries were running with?
