Understanding GoPay Help 513 on Your Account
Error 513 on royalwins typically surfaces when your GoPay wallet and your account details do not match during the payment handshake. This happens most often when the registered phone number on your GoPay app differs from the one linked to your royalwins account. The fix starts in your account settings: check your registered mobile number, make sure your GoPay wallet is active
and has cleared its daily limit, then retry the transaction. Players in Surabaya have flagged this most around peak evening hours when GoPay's gateway traffic is high — retrying after a short wait often resolves it without any account changes needed.
