Hi @juanpanie,
You need to check why the export to the S3 bucket is failing.
You can start by going to Admin Console->Batch Process Control and inputting an entry ID into the search box.
This will show the entire ingestion and export flow, including all the batch jobs that were attempted.
One of these will be “Storage Export”. You will get an indication of the job’s final status as well as some basic information about it. If you cannot determine what happened by looking there, you should check the storage export batch log[s] here:
/opt/kaltura/log/batch/storageexport-*$TIMESTAMP*.log
Note that fatal errors are logged into a separate file so you should have at least two log files, though the storageexport-$TIMESTAMP.err.log file may be empty. Go over both logs and grep for the entry ID to follow the flow and locate possible failures.
