For the second time now my F4-210 developed a problem where the GUI does not work any longer but gives an NGINX error page "403 Forbidden".

The first time this happened I followed instructions I found for resetting the device (boot without drives, start GUI, when it complains insert drives, and it will offer to re-install TOS, leaving user data untouched) but this is time-consuming. I would much rather figure out WHY this happens and fix it in a less invasive manner.

Any ideas?

Hi, please advise did you create any firewall rules before this happened?

No, I didn't create any firewall rules.

I found a work-around: if I call the GUI with http://tnas:8181/tos/index.php it works.

I am not very familiar with nginx; if this were apache I would guess that (a) dir listings are turned off, and (b) index.php is not recognized as an index file for some reason.

But I can live with it as it is.
