Message "you are not authorized to use this service"

[Tohnmeister]

Since yesterday I'm the proud owner of a DS212+. I configured my router so that I'm able to access the DSM from outside my network. Today I tried. It seems to work, but every few minutes I'm getting an error message saying "you are not authorized to use this service". If I click OK it logs me out and I have to log in again. If I log in again using the same browser instance, I will get the message immediately after logging in again. If I close my browser and log in again using a new browser session, it works again for several minutes.

I'm using Windows 7 64-bit and Chrome together with the latest DSM release (DSM 4.0-2198).

I have the same issue since I have upgraded to DSM 4.0-2197. It has something to do with the automatic logout timer. In case that timer has expired then the next time I try to login results in the message "you are not authorized to use this service". Only after restarting Chrome I'am able to login again.

Same problem here

Same issue here (although I do not need to restart Chrome to log in again right away). This automatic logout after just two or three minutes also breaks e.g. the Audio Station, as I get kicked out while listening to music.

Interestingly, this only happens to me when I am outside of my home network, logged in remotely as a user. Logged in as admin at home, I have no problems with session expiration.

Would anyone know how to extend the duration after which the session expires?

OK, I actually got mine solved by checking the box "Enhance browser compatibility by skipping IP checking", in Control Panel / DSM Settings / Security (I am behind a proxy). Now sessions don't expire anymore, at least not before the logout timer, which is set on the same settings sheet.

I can log in remotely to my DS212+ by accessing my IP:5000. I'll log in using an administrator account, and I can work with DSM for awhile - even play a tune on Audio Station. But eventually I will always get a warning pop up, "You are not authorized to use this service." What am I missing here?

I know this thread is a little old, but the fix here works:

My time was set to manual. I changed it in the control panel to update daily from a time server and voila! No more message that I am not authorized every 2 minutes.

(My time was about 15 min fast compared to real time)
