The most common cause is providing multiple times wrong credentials on log in. The IP address from which the login attempt was made is then blocked. There may be many reasons for such blocking, the most popular ones will be presented below.
Incorrect login attempts to email from a mail client
When you change your email account password, you will still try to log in with your old password in the email client on your computer/phone. After several wrong login attempts, the IP address will be blocked.
Incorrect login attempts to FTP account
Here too, your IP will be blocked after a few wrong login attempts. Please note that most FTP clients automatically reconnect if they fail to connect the first time.
Incorrect login attempts to cPanel or Webmail
Your IP can also be blocked, if you log in incorrectly to cPanel or when logging in to mail from the Webmail
