iPhone App Login Issue: “Unknown error” after reinstall/reset attempts

Oxsy — Wed, 06 May 2026 10:32:01 GMT

Hello everyone,

I am contacting you regarding a new issue that started affecting my Arlo iPhone application only. Whenever I open the app and try to log in, I receive an “Unknown error” message. The issue persists even after trying multiple troubleshooting steps from scratch.

What I already tried:

Reinstalling the Arlo app completely
Removing all app data
Restarting the iPhone
Resetting/changing my password
Logging in again with the updated credentials

Unfortunately, the result is always the same: “Unknown error”.

Important details:

The issue appears only on the iPhone application
Internet connection is stable
The problem started recently (~2 weeks ago)
I also recorded a screen video demonstrating the entire issue step-by-step:

Thank you in advance for your support.

The team is investigating the symptom. In the meantime, there's a workaround that should help you log in successfully.

Can you try the following?

Create a temporary Arlo account

Open the Arlo Secure app and tap Sign Up
Use a different email address to create a new account
Complete the setup and verify your email when prompted

Trust your device

Once logged into the temporary account, follow the on-screen prompts to trust your device
Confirm that you can fully access the app on this temporary account

Switch back to your original account

Log out of the temporary account (go to Settings > Log Out)
Log back in using your original Arlo account credentials
You should now be able to log in successfully
