Error while trying to use XRC

I read the following in the forum but i dont know how to “set your local network to be a system subnet” The XRC lives on a system subnet where making outcalls is free, so it’s not necessary for it to attach cycles. If you want it to work locally you have to set your local network to be a system subnet, too
