Database passive content index state stays FailedAndSuspended even after reseeding

I have a mailbox database with two copies in a database availability group, the active copy is healthy and its content index state reports healthy as well, the passive copy is healthy but its content index state reports FailedAndSuspended.

I tried the: Update-MailboxDatabaseCopy <DBName>\<ServerName> -CatalogOnly more than one time, it completes (says 100KB written) but the state never changes.

I even tried to manually stop the service>delete CI>start the service, the CI folder was recreated (about 1 GB) but still the state is still FailedAndSuspended.

Please Help!
