Product: Envy Photo 6255

I am using the HP Envy Photo 6255 with my Chromebook.  I use the HP app.  Scanning was working fine up until a week ago.  Now when I go to the app and select Scanning, one of two things happen - it either quickly flashes connecting to HP Services and then it brings be back to the previous screen or it asks me to log in to start scanning and when I try to log in, I get an error message that I do not understand.  Something like Invalid_Grant.  No idea what that means nor could I find any helpful information.  I have tried uninstalling/reinstalling the app, turning off and unplugging the printer, uninstalling/reinstalling the printer software and resetting the wifi for the printer and still the problem persists.  I'm hoping someone can help.  Thank you.

Thank you for responding. I actually found a fix after changing the way I asked my question when googling. I downloaded Chrome Dev browser and then when I got the option to sign into my HP account and it asked me which browser I wanted to use,

I selected the Dev browser and was able to successfully log in and am now able to Scan using the HP Smart app.  No more Invalid _Grant error.
