Cannot autheticate to comcast when using my home network

We had an outage Saturday night and since then the Xfinity app on my Roku is giving me an error 500.  Also on my laptop I can get to Xfinity.com but as soon as I click on the Sign In button I get a timeout error. 

I can get to all other websites woth no problem. 

On my phone every Xfinity app hangs when I try to sign in. 

If I turn off wifi on my phone and use mobile data I can login to any of the apps.  

Tech support has been useless. I've spent 5 hours on hold, chatting and talking with people.  Each one is as useless as the other. 

I went as far as to go to the local Xfinity store to swap out my router.  That didn't work. 

I've root caused the issue for them.  This is an authentication issue. But I can't fix it myself!

Anyone else have this issue before?

Maybe you've done this already.

Pick on the laptop for a test.  There is an authentication token stored as a cookie in your browser.  Try clearing web site data AND cookies for a test -- also wipes out active logins.   Close your browser.

Then reopen it again, and try to login.  It should re-prompt you for username/password and two-factor to get the authentication token again.  If you've done this already then never mind.  It's not going to help. 

***Only if the above works****

Roku is a bit harder.  Sometimes when an app gets wrapped around the axle, you have to delete the app -- also wipes out the app on all Roko's linked to the account.  Reboot the Roku's to clear memory.  Then reinstall the app from the Roku store -- adds the app back to all devices on the account.  You'll have to re-login on each device again to activate them again and store the login information locally on them again.

Thanks for the reply.  Unfortunately I've tried both of your suggestions but neither helped.
