Troubleshooting
During configuration, it's possible that the Twilio web page might redirect you
back to the Conversational Agents (Dialogflow CX) console with the warning Unable to authenticate with
Conversational Agents (Dialogflow CX). If this occurs, try the following actions to fix the issue:
Make sure that you've logged into your Twilio account in addition to your
Dialogflow account.
A browser extension might be blocking the redirect. Open an incognito window,
log into Dialogflow, and try the integration again. Make sure that
the setting Allow in Incognito is turned off for all extensions.
