Arlo Secure app UNKNOWN ERROR iPhone 17

[PMich]

I have been trying to troubleshoot the UNKNOWN ERROR which does not allow me to login to the Arlo Secure app on iPhone 17 for the past 15 days but the Arlo support has not been able to resolve.

This is Case No. 45099975 which has been escalated according to Arlo support, but no resolution since more than two weeks. 

The Arlo Secure app works well on my older iPhone 16, and on a computer.

• Now it is the fourth week seeking support from Arlo and still no resolution.

Many years ago, there was a telephone number to call to speak to Arlo technical support, which has been discontinued. Now, the only way to speak to Arlo technical support is to request a call through Arlo Secure app. However, when the Arlo Secure app doesn’t work because of issues such as the current one where the app doesn’t install or cannot be logged into on the new iPhone 17, there is no option to reach Arlo technical support. 

Being an Arlo customer since the beginning of Arlo systems with 25 to 30 cameras, it is not productive.

I get the same message and all types of resetting and reinstalling you think of, there are 2 problems no one from Alro wants to speak to a live person and they don't know what the problem is. I spent a lot of my on this product and because i got a new Iphone 17 it doesn't work.

Now I am in the FIFTH week trying to resolve this issue of Arlo Secure app’s incompatibility with iPhone 17 or the current version of latest IOS.

With this kind of delay, I am delinquent in returning my older iPhone 16 back to Apple for trade-in. And I have to keep the iPhone 16 because only through the working Arlo Secure app on it I can contact Arlo telephone support. 

Maybe it is time for me to trash my whole Arlo system and switch to a better system.

Now I am in the SIXTH week trying to resolve this issue of Arlo Secure app’s incompatibility with iPhone 17 or the current version of latest IOS.

Is this issue with all iPhone 17s or only mine?

Can you try offloading the app as well with these steps:

1. Open Settings.

Tap General → iPhone Storage.

Scroll down and tap Arlo Secure.

Tap Offload App → confirm by tapping Offload App again.

This will remove the app but keep all your app data (like your login info and settings).

2. Go back to your Home Screen.

You’ll still see the Arlo Secure app icon, but it will have a small cloud download symbol next to it.

Tap the app icon, our iPhone will reinstall it automatically from the App Store.

Once it finishes downloading, the app will open normally.

Did all those steps. Still get the same error and the app does not log in. Please see attached screen shot from this afternoon.

Thank you, I will inform the team now.

The app still works properly on my iPhone 16 which has iOS Version 18.6.2. Because of the issues on the iPhone 17 having the latest iOS 26, I have not updated the iPhone 16 to the latest iOS 26.
