Hi @mostafa2mahmou. Welcome to GoDaddy Community!
That message usually means that there is a temporary block on your IP address. You can try waiting for the block to be removed, or try from a different location/network.
Blocks of this nature are generally caused by malicious activity being detected from an IP address. If you are using a shared network, such as a university or company network or a public wifi, it might not be related to something you've done. This can also be the case if you are using a VPN or a proxy. Hope that helps.
