DLNA Error 7531 on PS3

Hello,


Everything worked for 2 years. Now, I'm on DSM 2.3 and PS3 3.10 and I can no longer access my Synology DS107+

I get DLNA error 7531 on the PS3. I've rebooted both devices, router, cable modem, re-indexed the DS... nothing.



Anyone have any suggestions? 

Thanks















I didn't find the right solution from the internet.
