NAS Webinterface not reachable

[sliver]

My NAS is not reachable over the web interface.

 

I´m now on 5.0-4528 Update 2

 

Since I installed the update I never had problems with it.

 

Now I can access the data on the NAS ( AFP ) and the Synology Assistant finds it, but the Webinterface is not reachable.

 

I also restarted several times.

 

Any ideas what I can do?

Restarted the router.

 

Now its working again.
