Problems with the DLNA function of my NAS

[ALN118]

Hay Guys 

 

I have a problem with my NAS and dont now how to fix it and hope you guys can help me =)

 

I have a Fujitsu Celvin NAS q700 which uses Twonky Server (Version 6.0.39) for DLNA. 

 

But since a few weeks every time i watch a movie over DLNA the Connection fails after about 20-30 Mins and i have to reconnect to the DLNA service. (If i watch the Movie with my PC (Without the DLNA) there are no Problems)

 

I already Updatet the Firmware of my NAS and checked if i can change anything in the Twonky Server settings.

 

There is a newer Version of Twonky server but i dont get it from Fujitsu and i dont think i can update it manually.

 

I added the Logfile if you wanne look into it =)

 

If something isent clear or i missed Information pls ask
