C9800 17.2.1 zero day configuration

[Piotr Grabowski]

Hi, I've just updated my C9800-L to IOS-XE 17.2.1. I'd like to test the zero day configuration via website but the standard credentials (webui / <serial number>) does not work.

Do you know if it was changed in the new release?

Have you tried using both the 1st port and or the service port?

[Piotr Grabowski]

Just checked it and the funny thing is that now it doesn't work at all :)

I've tried with 1st interface, got an IP address but it looks like a web server issue:

An error occurred.
Sorry, the page you are looking for is currently unavailable.
Please try again later.

If you are the system administrator of this resource then you should check the error log for details.

Faithfully yours, nginx.

I did a format flash:, installed the software from a scratch but it doesn't helped - still the above error.

I'm not getting an IP while connected to a service port, what should I do to fix the issue?

You probably need to use the startup wizard on the cli.
