I am not able to create ebay sandbox account to this link https://developer.ebay.com/DevZone/sandboxuser/.
I looked in the developer tools and saw the error response of the server: "An error number "REG.BIZ.0" occurred while processing your request.", "eBay API failed".
I have tried it for different username, password, email but always get error "An error occured".
Please do the needful.
