hikvision mobile apps - ivms-4500 / ezviz only work on wifi, not mobile network

You shouldn't need to adjust any of these settings. No port forwarding or advanced router settings need to be changed, I think it's either a problem with the service or we both have the incorrect settings. I have tried everything. I have another recorder tested on a few different sites, P2P different brand and works fine.

how to config mobile ezviz
 
1. Go to www.ezviz7.com create account (if u dont have one)
2. Set ur DVR/NVR/IPC, Configuration - Network - Platform access/Extranet access - checklist enable cloud P2P ( enabled by default )
3. Download the app on android or iOS (ivms-4500 / Ezviz)
4. Add Device on iVms/Ezviz app, by barcode scan or manually input the serial number of ur device, then u will be asked for verification code, u can check ur verification code at the bottom of ur DVR/NVR/IPC. it should be 6 Random character.
or u can check it from DVR menu Configuration - Network - Extranet access ( only for Back-End Device such as DVRs & NVRs )
for IPC u should look at the stamp near the brand and serial number stamped on the bottom of ur IPC case.
5. after u input the verification code, there u go. :headphones: u can preview ur cam at gallery / home tab on iVMS-4500/Ezviz app
 
So far everything is working well with my camera except for mobile apps on the cellular network. If I am on any wifi network, local or work or even public, the mobile apps work just fine. If I am on verizon's 4g mobile network, I get a connection error. Even on cellular, I can log in to the app via the ezviz cloud and see the camera listed.. It just wont connect. The second I turn wifi on (doesn't matter if its my local wifi, work, or even public) it works great. I could have sworn last week when I set it up, it was working on both.. now this week its not. Any thoughts? I don't see it being a porting issue since the wifi networks outside of the home are coming in on the internet.


I checked my PC's IP address by typing ping.eu, and found that my IP address was changed and different from my NVR and my port closed. I opened my apps' device config and typed the new assigned ip address, and then I opened my router to add the closed port. It worked. I now able to see my video away from wifi.
