APC PDU AP7920 Web-Interface

[Der_OPT]

Hello everyone,
I have the following problem:
The AP7920 reliably receives its network settings via DHCP. Login via telnet or FTP works.
However, logging in via the web interface is not possible: "There was a problem loading the application. Please login to the device via telnet for more details."

In the network settings, it looks like this:

------- Web/SSL/TLS --------

1- Access: Enabled
2- SSL/TLS: Disabled
3- HTTP Port: 80
4- HTTPS Port: 443
5- Advanced SSL/TLS Configuration
6- Accept Changes

All outlets are disabled. If you log in via telnet as Device Manager, there is no way to configure anything.

Is there a way to make the device usable again via telnet or even better via web? Do I need the serial cable?

have you tried another browser?

Yes, Firefox and Opera on Linux.
I'll try Edge tomorrow.

The device is working perfectly again. I unplugged the device for about 10 minutes. After that, everything worked as it should. Apparently, the full reset only took place after that.
Thank you for your support.
