Device Manager not loading in web browser or iPhone app

[jamestco]

Since I deleted dozen of devices from my router, I can no longer load the device manager in a web browser or on the app. The phone app says "Sorry, the action was failed. Please try again." The web browser "This R-App is not loaded yet, please try again in a minute."

Please help.

I just would like to add that other sections like network monitor have the same error message.

Reboot the router and it should resolve the issue and allow you to access properly again.
