Blue Iris

Hello, im having a sudden issue where i cannot connect to Blue Iris on only one of my two phones, only over wifi, over cellular it works fine.

So both iPhones are connected to the same WIFI, one phone will connect to the blue iris server, one will not. Prior to this, they both connected perfectly for years.

All IP's are correct, all ports are correct, its just one refuses to connect when its on the WIFI network, cannot even bring up the server in a browser.

Any ideas for this strange issue?

go to
settings
general
transfer or reset
reset
reset network settings
log back into your Wi-Fi again

if still no luck
press volume up then volume down let go and then hold power button in until you see an apple then let go off power button.
