I had a similar issue but with mine I was seeing the advanced web interface but some features within it were not working. For an error message in the non-working portions of the interface, it stated 'IOS is inaccessible or down'.
I noticed that if I removed the access-class for ip http that it was fully functional.
Apparently at least the ASR1013 communicates with an internal service.
if you run 'show ip http server all' you get a netstat output like this:
Note: I replaced my IP with #.#.#.# in the output.
HTTP server history:

Notice that there is internal communication with the web service on IP addresses 192.168.1.2 and 192.168.1.1. I had to add 192.168.1.1 to my access-list and re-add the ip http access-class statement. Once I did that full functionality to the website was available.
Thus, you may have issues with an assigned access-list to your ip http config. It may even prevent your advanced web interface from working.
Something to check. Btw, I do not have these 192.168.1.x IP addresses in my configuration at all.
