I'm trying to add access to Netbox (https://github.com/netbox-community/netbox/) as a web resource on our PCS. There's a demo version here: https://demo.netbox.dev
Although it loads up, it's clearly not correct - the menu on the left isn't shown correctly and does not expand automatically. None of the links in the menu work either.
My guess is it's a header rewrite problem or other, but how does one go about debugging this?
I'm slightly perplexed how complex pages such as VMware VCSA in HTML5 work flawlessly but something like this which seems quite trivial does not.
Thanks for any pointers.
