Been using IPCam for many months, successful with 4G carrier access and internal access and DDNS access. New enterprise WiFi network at work seems to be blocking something, did not have any issues before the office WiFi upgrade. 4G in the building is poor so smartphone relies on WiFi coverage for everything. Using IP Camera v6.2.7 on Samsung S5, a camera setting like: mycam.ddns.net port 84 no longer works BUT in the phone browser (Chrome), mycam.ddns.net:84 goes to the camera login page, I can login and see and control the camera. I can get to the cameras and control them when at home, when on 4G, when using hotel WiFi - basically everywhere but on the new work wifi. The interesting aspect is that it does not seem to be that ports are blocked since the mobile browser does work on the same network. The IT guys at work are not aware of anything they are doing differently than before. I should mention that there are other users of IP Camera at the office having similar problems now. Is there something I can ask the IT guys to check? Is there a setting in IP Camera that will allow it to work on this new wifi network as the browser does?
