I cannot access my site and email from my home network but it works on other computers and devices.

This is most likely an IP address block. Our servers use a centralized firewall that detects multiple failed logins to the server, port scanning(very common with Apple devices), simultaneous connections, and even a weak network connection from your IP address can trigger a block. Whether it’s http, mail, cPanel, webmail, ftp, and mod security failed login attempts will block an IP address for security reasons. To correct this you can call Lunarpages support or send an email to ipblocks@lunarpages.com and a tech will remove the IP address from the servers firewall deny list.
