What’s happening?
The customer is encountering an error message stating "You are offline. This is a read-only version of the page." after the site's authentication key expired and was revalidated.
Reason:
This is caused by the Content Security Policy not being properly configured in the site settings.
Resolution:
- Verify that the Content Security Policy is correctly set up in the site settings.
- It is recommended to configure the CSP directive with the value: script-src https: 'nonce'.
- Ensure that the authentication key has not expired and renew it if necessary using the site authentication management.
- Check if an application user is created for the site in the Dataverse organization and confirm its existence using the site checker.
- Ensure that the Dataverse organization where the site is created is running and not in maintenance mode.
- Verify that the connected environment URL of Microsoft Dataverse has not changed and update it if necessary.
- Confirm that the site registration is present and active in the portal management application.
- Use the Devtool extension to debug the site to identify the root cause of the problem.
- Review error logs by disabling custom error logging to find detailed exceptions.
- Execute the site checker to resolve any configuration issues.
