DS-2CD2532F-IS problem with isms 4500 after getting back to V5.2.5 build 141201

[Ranma64]

Hi everybody and thanks for your guides to unbrick Chinese cameras after 5.3.0 firmware update and getting back to 5.2.5.
Everything works fine now, but i cannot access 2 of the 3 downgraded DS-2CD2532F-IS using iOS App iVMS-4500: the only one reachable can be reached both via Ip/domain and via HiDDNS on the iVMS-4500 app. The other 2 can only be reached using Safari on a pc or mac:On the hik-online webpage all 3 cameras are perfectly reachable.
really strange .
can you help me?
thanks
Max

hi i just joined because its taken me over a year to install my cameras (don't ask).
I upgraded to latest firmware.
I am having very weird IVMS-4500 issues trying to get connections working.
I can't get any direct connections to work when using the upnp and hiddns options
When i manualy open a port for each of the cameras that works fine.
The P2P works fine too (but only seems to allow access to the substream)

Bottom line this is weird until i figure out if ivms changed, the firmware or my ubiquiti router doesn't like the cameras....
