Is anybody else getting an access denied error 1015 message? I know I tend to check my account balance a lot but that's cause I just invested another 60$ through one of my exchange wallets and was worried. Hopefully this is just a momentary issue.
Your hunch was correct. You have checked your balance too often. Error 1015 is a rate limit error to prevent the site from going down. Could be on a individual level or for a range of addresses.
