Error 404 when starting the web app

(1) ShareShare
ReportReport
Posted on by 2



Hi everyone,

When I start the app via the Microsoft 365 Copilot app, I receive a 404 error with the following details:

Time: Tue, 28 Jan 2025 08:56:36 GMT
Session ID: c6458c20-dd55-11ef-943d-b7f7569c1e1c

Additionally, when I click on the profile icon, essential information such as my email is not displayed. The picture of my profile is filled with a question mark.

The image above illustrates these issues, which I hope will help in resolving them.

Thank you for your support.

    Hi,
     
    If your profile is missing that means you are not logged in and is the root cause.  Here's what I would do:
     
    1)  Remove all cookies
    2)  Close browser
    3)  Restart computer
    4)  On restart, then go to https://www.office.com/ and confirm you are logged in (check profile).
