Advanced Suggestions
• If your computer is connected to the WAN port or is connected wirelessly, use a
computer that is connected to an ETHERNET port.
• Try to access the P-2812HNU-51c using another service, such as Telnet. If you
can access the P-2812HNU-51c, check the remote management settings and
firewall rules to find out why the P-2812HNU-51c does not respond to HTTPS.
