Blink provides affordable smart home security solutions.

Blink is an initiative that provides affordable smart home security devices. It deals with devices like security cameras and video doorbells to ensure home security. Moreover, the devices can be accessed directly from users’ smartphones. This is obviously a handy feature as it enables users to monitor their homes wherever they are. While all of this sounds like Blink might be a great addition to your home security, it is not without its pitfalls. A lot of Blink device users have recently complained about experiencing the Blink Cloud Error 503. If you are experiencing similar issues with your Blink device read on to see what it is and how you can fix it.

Blink Cloud Error 503

What Is It?

Since Error 503 is an HTTP error that occurs when the server is not available when the web browser is trying to connect to it, we have to assume that this is an error on the part of Blink servers. Due to this, users that have armed their cameras get the Error 503 notification when they try to disarm it. A few users have complained that their cameras stopped working completely due to the Blink Cloud Error 503. This is obviously a problematic situation as users are not able to avail the home security services promised by Blink. Moreover, a lot of users have also complained that they encountered this issue after updating the app.

Power Cycle The Camera
