Here is a list of the most commonly known reasons why the sources cannot be verified:
Active Ad-blocker extensions in a browser, or any applications that have a similar feature.
You are currently logged into the wrong channel account with no access to the sources.
Permissions to the sources were revoked by a client or by someone else.
The channel account password was changed due to security reasons.
The channel account was deleted and is no longer available.
The channel is having issues on their end that we have no control over.
In case of any potential issues mentioned above, we recommend taking the following actions:
Make sure to disable any active ad blockers.
Check if any permissions were revoked to sources that you are trying to verify. We recommend checking if the channel account that added the sources, is still able to view data for sources that cannot be verified.
