Yes, I have an idea. Perhaps the location is detecting your AV's age and are restricting access to accounts that have been in existance for over a certain length of time, for instance 30 days. If this is the case then you have no option but to wait that length of time before your AV can visit that location. I'm not saying that the restriction is 30 days, it could be 5, it could be 180 or any other number ... to find out the number contact the owner of the land. Until your av is old enough to visit this area why not take the time to visit many of the other places that are available to you.
