Devo accedere al NAS senza avere una connessione Internet disponibile
Qualcuno sa dirmi come posso fare?
Il NAS era collegato ad un router, ma ricollegando tutto allo stesso modo non lo trova

I need to access the NAS without an available Internet connection
Can someone tell me how I can do it?
The NAS was connected to a router, but reconnecting everything in the same way does not find it

Please use English in this forum or at least post in both your native and english language translations.

to access the NAS you type in the local IP Address of the NAS in a browser with port 8080 like so:

http://xxx.xxx.xxx.xxx:8080

failing that, use the QNAP Finder app.

it sounds like your NAS has reconnected to the network and picked up a new IP address. you must assign a static IP and not an automatically assigned DHCP address.

Hi, Simon
Thankyou for your answer
Using the QNAP Finder the NAS is detected, but it won’t connect
Also in the MAC finder
The error message tells that the server not exists or is not available
Even if i connect it by LAN to the Mac
How could it be?

have you had any power outage or a change in network structure at all?

does the QFinder app show the correct IP address?

do you even get a webpage to log into the NAS or just a blank screen?

what NAS model and firmware are you using?

I had the NAS connect to another place, that I had to leave
I don’t know if the IP address is correct, but is the first time I use QFinder, so I think it is
The webpage goes out of time connection
The NAS is a TS-212 and the version 4.3.3.2784

did you set a static IP on this NAS when it was in another place?

does QFinder show the IP address? And is it in the same network and subnet as the one it is now connected too?
