I am running the current version 4.0.1.9 and recently added two of the TOP-201 cameras (http://www.ipcamtalk.com/showthread...20P-HD-IP-Cam-(The-Cheapest-IP-Cam-So-Far-!!)) and deleted one user group and replaced it with another group. I can log in to view the webserver from my main PC on my LAN as usual, but two other PCs on my LAN cannot access it anymore. Also, my Android app on my Galaxy S4 is working fine with all camera streams viewable as expected. Has anyone else had a similar problem? Thanks.
