My firmware is V1.0.09 so I would think yours should have one if you're on the newer firmware. I'm not sure what's wrong, if I enter the IP address alone it redirects me to the panel.

When I got my camera out of storage (3 years) the panel was buggy until I reset to factory defaults. I'm not sure if resetting will resolve the issue you're having but if it's a similar issue it might. Here is the API command that works for me, since you can't access the panel to do it.

If most of the API still works you could probably just download a local copy of the panel.
