Tell us what happens instead
I just get a blank screen. I should say when I did this the first time, it worked. I could use ownCloud. I could see and use my external drive. I pulled a file off and save it to another area to make sure everything was working. Once I left the owncloud, and came back, everything was gone. I have been unable to access it again. I'm doing this on the raspberry pi, so I formatted the SD card, reinstalled the os, and tried to duplicate but have no luck at all. I've been through about 7 different tutorials and can't get a working result. I keep getting my SSL refused by my browser, though I have a paid DNS through godaddy.
