SSO (Single Sign On) - "Error Validating Code" and other failure messages

If you sign in to your site using a Single Sign On link, you may be unable to login and see a message like "Error validating code. Possible timeout. Try again."

That error is coming from your organization's internal IT system. If it persists, you need to contact them.

The message can vary. Your site administrators can replace that generic message with better instructions.

Site administrators: This is most commonly seen with Microsoft Azure and is frequently an expired client secret.
