Upgraded to BlueIris 5. Upgrade went smooth. Configuration files migrated well and all cameras appear to be working correctly. BUT the iPhone application can no longer connect. Even within the same Wifi LAN. Even through cellular WAN. (each time making sure that only wifi was on, but cellular off, or visa versa to check that route) The iPhone app just will not connect. Troubleshooting steps I have taken: - Ensured both BlueIris on Security PC and iPhone application have same configurations (key, ip addresses, usernames, passwords). - Checked multiple locations on Security PC to ensure authentic user, password etc. - Rebooted Security PC with the new BlueIris v5 - Rebooted iPhone - Uninstalled and reinstalled BlueIris on iPhone. Reconfigured to ensure matching to Security PC BlueIris. SO FAR NOTHING HAS WORKED. Is anyone else having this issue?
