Upon having completed the Parallels Plesk installation, you may find that you’re unable to login to the Plesk panel. The reason for being unable to do so is because the Plesk ports are being blocked by your firewall. To resolve this issue, please follow the step-by-step directions outlined below:
# iptables -F
Once the above command has been run within Linux, you should now be able to login to your Plesk panel admin area for further configuration.
Should you have any further questions pertaining to your Plesk license, please feel free to get in contact with our web hosting support team for additional assistance.
