Bridge 11.1 does not recognize files on Synology NAS

Hello, since a week Adobe bridge does not recognize the file-types on my Synology 218+ NAS any more. "Sometimes it sees them as "binary doc" with file-size 0, sometimes it just does not see them at all.

When it sees folders and/or files, it shows them as "locked".

I removed the index on the NAS and re-indexed the folders. Nothing helped. Sometimes the reaction of Bridge changes (it sees more or less files or sub-maps), it is not predictable wht you see. All other applications (like Photoshop) have no problems with the NAS.

Advie from Synology was upgarding to latest software and stop and restart indexing, which I all did. I re-installed Bridge.

Nothing helped. Any idea?
