# Resolving tag-sync errors in myApplications
<a name="sync-error"></a>

This section describes common tag-sync errors and how to resolve them. After attempting to resolve the error, you can retry the failed tag-sync task. 
+ **Insufficient permissions** — You do not have the required minimum permissions to start, update, or cancel the tag-sync. Review [Tag-sync required permissions](https://docs.aws.amazon.com/servicecatalog/latest/arguide/app-tag-sync.html#tag-sync-role) for more information. After ensuring the role you specify to perform the tag-sync has the minimum required permissions, retry the failed tag-sync task. 
+ **Already exists** — A task with this tag key-value pair already exists for this application. An application can support more than one tag-sync, but each tag-sync must have a different tag key-value pair. After you specify a different tag key-value pair, retry the failed tag-sync task. 
+ **Maximum limit reached** — You have reached the maximum of 100 tag-sync tasks per account, across all applications.
