Ports that can be blocked that would restrict cPanel access:
- cPanel login - port 2082 and 2083
- Webmail login - port 2095 and 2096
- WHM login - port 2086 and 2087
If you are unable to access your cPanel, Webmail and or WHM (if you are a reseller), you should be able to access it using the following (replacing yourdomain.com with your actual domain name):
http://cpanel.yourdomain.com
http://whm.yourdomain.com
http://webmail.yourdomain.com
For this to work, you need to be using Arivxe nameservers. Else, you will need to create A records for each subdomain so they point to our server using an IP provided by our support department.
