Chromebook changes preventing College google account login?

[mfoley]

We are having an issue with students unable to login to a secondary google account through our community college, On our chromebooks, I did not have any issues last year. 

It brings up a window saying "chrome-signin is blocked. Your organization doesn't allow you to view this site."

I have the three domains I am aware of that our college uses for their accounts .edu subdoman.college.edu and cc.ia.us domains.    in the sighn-in to secondary accounts setting

I hate to sound condescending, are you certain of the following two items

1. You have their current URL's. Some like to make changes
2. Is your Sign Into Secondary accounts set differently for these student's OU?

Wish I had a "Here is the issue" answer. We have not had any issues with our college course students yet.

This question was asked via Reddit /rgsuite with their applied solution. There was a change to GAC that has affected some districts.
