I believe there is a problem with firmware 1.04.15. I have a DCS-934L recently is showing up as offline in mydlink.com
No longer I'm able to connect to this camera via its ip address with Google Chrome. I found that it works with Firefox browser.
I compare the firmware on DCS-934L that works (Chrome, show up connected with mydlink.com) and one that doesn't work - difference is firmware.
I downgrade firmware to 1.03.01 - and now this camera is accessible via google chrome via IP address. However camera still up as offline in mydlink.com
