Some day both indexes on content delivery servers stopped updating (on publish end). I have searched the internet, "failed requests tracing" is not enabled, the default\anonymous user has read access in web db and tried the https://github.com/sitecoresupport/Sitecore.Support.404817/releases

Exception: System.NullReferenceException Message: Object reference not set to an instance of an object.

  • What index update strategy are you using? Is the error you have shared from the crawling logs? Do you see references to indexing process starting in crawling log? Have you made any changes to web DB recently? Have you removed any roles? Commented May 22, 2023 at 13:50
  • OnPublishEndAsync, no from the log.txt No, No, no, it stoped one day without any change in the system Commented May 24, 2023 at 13:51

Reset to default

It looks like the default\Anonymous user is corrupted. I overrided the RaiseQueuedEvents method and switched the context user to extranet\Anonymous for all events. It works fine now. Set the new provider in the next tag:

add name="sitecore" type="Sitecore.Eventing.EventProvider, Sitecore.Kernel" systemDatabaseName="core"
