When CaliberMind identifies an issue with one of your connections, it would notify all Admins on the account of that issue via email:

Admins will keep getting daily email reminders till they come back to reconnect. Then, once an Admin reconnects, CaliberMind will send a follow-up email to notify all Admins of the re-connection:

When you have received such a notification, log into my.calibermind.com and find the connectors section under “settings”. Select the appropriate connector category (Pull/Push connector). From there, follow the directions listed on the connector to re-authenticate it.
Reach out to moc.dnimrebilacobfsctd-343fb9@troppus if you continue to encounter re-authentication issues.
