I have a user who constantly gets the “Oops… Looks like something went wrong.” error page after successfully authenticating to access their Microsoft 365 web apps in Firefox on one specific Windows10 device. (Error page prompts after authentication, which shows successful)
However, they can authenticate and access their M365 apps without any issue from Chromium based web browsers on this same device.
I’m a relatively new Duo administrator for my organization, so I was just posting to see if any has seen a similar issue (sorry if I sound daft). I’ve already tried the basic Win10 desktop troubleshooting techniques, e.g. cleared cookies & cached data, completely removed Firefox and its app data followed by a clean install of the app, and even had the user replicate the same issue in another user profile on the device.
