Three pan cam v1 cams suddenly stopped responding

Two days ago, my three cam pans stopped responding to the app. Nothing in my setup has changed…same internet, same router. I also have a Cam Pan v3 that still works fine. The firmware for the three v1 cams is 4.10.9.3006, and it reports that it is the up-to-date version. I get the flashing blue light, and the camera is still recording to the SD card, but does not respond to the app at all. You can’t change settings and you can’t live stream. I tried doing a factory reset on one of them, but that changed nothing. I also shut off every internet connected device in the house, just to be sure no other device was causing problems, but the problems are still there. I’m out of ideas…anybody have any suggestions? Thanks in advance.

For whatever it’s worth, I have two original Pan cameras with the same firmware version as you. Both are working fine.
