What do you do when you try to add on a key image on the asset store plugin and it says this

Error adding key image

Could not create package: Error receiving response from server (403): The remote server returned an error: (403) Forbidden.

Any help will do

Had the same problem, but rebooting Unity fixed it. Probably some time-out from the server.
