File Repository Server is down Import Wizard

Hi experts,

After installing from BOE XI 3.1 SP7 FP3 i'm facing some strange erros using import wizard:

Failed to update universe file. Reason: File Repository Server error : Failed to connect to the File Repository Server Input. Make sure the server is up and running.

This happens with some universes, folders and webi reports work well.

Both File Input File Repository Server and Output Repository server are running in source and destination environments,

And to put things worst the apparently well migrated universes get the si_path property lost, so the link between CMS and File system is lost.

Any ideia ?
