"You are logged in but we are unable to access your account details."

Hello, @huangallan, thank you for reaching out to our forum for help with that login error message you're running into. Those are never fun to deal with, but I have your back on this. Are you only getting this error on the My Account app? Are you able to try on a different device or confirm if the same issue persists on the Xfinity website?

Hi Marcos,

Sorry for the late reply, trying to reply on mobile kept giving me a 431 "header too large" error, so now I am hotspotting to my computer. To answer your questions, I am still experiencing all of these issues - “you are logged in, but we are unable to get your account details” on the MyAccount app, the login loop on the Xfinity app (I have tried uninstall-reinstalling, and also clearing my default browser history/cache), and the same issue to logging into via the browser of "Hmmm, the page didn't load correctly" also persists into my computer browser as well.

Does this log in error occur on different devices?

Yes, the "page didn't load correctly" does occur on both my phone and computer. However, my main concern is the xfinity app login loop, since I need to setup my internet. I only have my phone to try to login through this app.

Just chatted with another rep, got it resolved! The ID I was using wasn't linked to my account properly, so I chose the option to create an ID, and it linked my accounts. Login worked fine after that!
