Geovision 800 GV-AView App on new Samsung S8+ showing only "Loading"

No video Streaming, stuck at "Loading".

Solution via online support page(top right corner of page "Enter Live Chat"), Christine:

1. close GV main software.
2. Go to C:\GV-800\WebTemp and delete all jpg & gif files (do not worry about its subfolders such as ..\images, etc.)
3. run main software again and connect via android app.
4. It works!

PS: Prior to this, we tried two methods (which weren't the solutions for me):

1. on main software > Network > Check GeoHttp under Server tab & Mobile tab, check jpeg under JPG tab. In my case, they were already checked. Didn't work.
2. use camyouseeme.org to test if server ports: 81 (not 80 in my case), 4550, 5550 & 8866 are not blocked by ISP. None are blocked, only port 80 is timed out but I don't use port 80, therefore on the mobile app, I had to enter server ip as xxx.xxx.xxx.xxx:81 instead. Though port field is 8866.

The chat script is in my Yahoo email box. Very impressed by the tech support.
