"Application error: a client-side exception has occurred"

robincumming — Thu, 30 Oct 2025 10:31:19 GMT

I am trying to access my online account to download bills etc but whenever I try to access it I get an error message saying

"Application error: a client-side exception has occurred (see the browser console for more information)."

It's been like this for months since switching from BT to EE. I always can't see any of my account information or check my guaranteed speeds etc.

It's the same problem whether accessing on a browser, mobile or on the app.

Any solutions?

Hello @robincumming ,

Welcome to the community,

I would suggest you ring customer service by pressing option 2, which will get you through to one of the guides, and ask for an account refresh, that should solve it. Delete the app and reinstall it and register again.
