Are you using firefox?

[fastness]

It seems firefox is related to "The image http://admin:admin@192.168.11.91:8080/?action=stream is not available because it contains errors.

I switch to MS windows + IE
at the Gargoyle, The preview shows a blank windows. No preview.
with win+IE, Visit http://192.168.11.91:8080/?action=stream, get no picture and the screen repeat those lines

understand it only worked with firefox

I don't think that feature is maintained anymore?

I suspect it will work with a very old version of firefox?
