Hi GR, Thank you for reporting this Bug.
This is now fixed and updated in Version 1.5 of Control Cube. V1.4 is already submitted to apple and will take 2-3 more days to be out. While v1.5 will take approximately 7 days from today.
When you want to add the FOSCAM to V1.5, make sure first to create a new User in the FOSCAM user settings. The user can be a "Visitor" not Admin. set any username and password. For example username is GR and pass GR. Then in Control Cube. Add WebView->under URL you should specify the following exactly:
btw, with without "http://" will not matter, the app corrects the URL on its own.
Also, this should work on pretty much any camera not necessarily FOSCAM.
I have tested this on a FOSCAM and it works perfectly, thanks for your patience
