Hik-Connect Hikvision - Two out of four cameras offline after changing internet provider?

[i_mitchell]

Hi, today I changed internet provider and could not get the cameras to work. I followed the thread for changing IP addresses, downloaded the Hik Partner Pro app and changed the IP address. Two of the four cameras are now visible but two are now offline, I have tried turning the TP links off and on on and have rebooted the recorder but still two cameras are offline. Any advice on what I should do?
Best regards,
Ian
