Your previous answers stated it wasn't a real place and not on earth. Most fictional places not on earth are on other planets, so I started working my way through this list here: https://en.wikipedia.org/wiki/List_of_fictional_planets_by_medium but I was a bit lucky because I noticed after trying about 25 planets, an oddity on that page, Star Gate was conspicuously missing even though it's linked to from this page https://en.wikipedia.org/wiki/Planets_in_science_fiction, so I started on Star Gate planets link which was this https://en.wikipedia.org/wiki/Stargate_%28device%29#Addresses but that page wasn't really a list of planets and google found me a better one here: http://stargate.wikia.com/wiki/Category:Planets . The first link is Asgard-controlled, and the 4th link on there is Orilla.

Pretty straightforward thought process, no?
