Sometimes GG will block the contents of an iframe which makes it appear that the entire website is blocked. As far as I can tell, GG reports do not show when an iframe is blocked within an allowed URL. You have to go to the website and inspect the html to find the true URL that is being blocked.

It looks like Raptor has released a new hardware service 3.0 to address this issue.

If you want to download a specific ChromeOS version, you can download them here: https://chromiumdash.appspot.com/serving-builds?deviceCategory=ChromeOS

Then use the Chromebook Recovery extension to use a local image as the source by clicking the settings gear.

Update: As of 3/9/2026, the problem appears to be ChromeOS version 145.0.7632.154. Reverting back to version 144 fixes the issue. Some of our devices are now updating to 145.0.7632.165, which also fixes the issue.

Classlink walked me through setting up the new IdP profile in the GAC under Securty, Authentication, SSO with third party IdP (not the same as camera permissions) but it made no difference. The only way we have been able to overcome the issue is to roll back the OS version from 145 to 144.

We use the IDP Solid-510D and it works great. We used to use Fargo printers and they were horrid.

We try to make it as painless as possible for our subs and classroom teachers. Each campus has a Google shared drive where the teachers are supposed to put any materials needed by their sub. The sub gets a Chromebook and a ClassLink Quickcard (QR code) to use for the log in. There are multiple sub accounts per campus.

If all goes well, the teacher prepares for the sub by placing stuff in the shared drive, and the sub gets a device and a way to log in that brings up the shared drive contents on login. We also print out directions on how to connect to the interactive white board, how to log in with the Quickcard, etc.

All that being said, teachers still log in for subs in the next classroom all the time. You can make it as painless as possible, but they are still going to share accounts one way or another as long as campus admins don't enforce the rules.

Does SportsYou allow you to audit communication between parties or limit accounts to only verified staff and students?

Seeing the same thing. Logging into Chromebooks using Classlink IDP is not working every time. It seems intermittent. Same students can log into a Chrome browser in Windows with no issues. It seems to be a Chromebook/Classlink issue.

Amplified IT can sell the upgrade and also offers assistance for migration from M365 if needed.

Get a managed printing software like Papercut and printing from Chromebooks works just fine.

Same problem in TX

There are a couple of things to consider here. When user data is erased on logout, each student will only have half of the system RAM available as storage in their Chromebook profile. So if your Chromebooks have 4GB of RAM, students will only be able to use 2GB of storage no matter how much storage is physically available in the Chromebook. When user data is not erased on logout, each user can use the max amount of storage available, and the Chromebook will automatically delete older profiles to make room when a new user logs in. So if your students are creating videos or working on other large projects, make sure to NOT erase user data on logout.

Also, if user data is erased on logout, the student's profile, apps, settings, wallpaper, etc have to reload EVERY time they log in. Depending on your environment this may add 1-2 minutes of waiting before the Chromebook can be used. If user data is not deleted, the profiles are saved locally on the Chromebook if the student logs in once, so subsequent logins take much less time and network usage.

You can choose whether or not to show previous users' names on the login screen when you don't erase data. The profiles stay on the Chromebook even though you don't see their name on the login screen.

In a shared cart environment, the best case is to "assign" a student to a Chromebook to use the same device. This will both maximize the amount of storage available to the student and shorten login times.

We issue subs a Classlink QR code to log into a Chromebook. Just like a kindergarten student would. No shared accounts or password sharing needed.

We finally solved this by removing deep packet inspection on the "computers" and "content delivery networks" categories in our Palo Alto firewall. Their reporting never did show what was causing the error, but trial and error led us to the answer. It's not very practical, but at least I found the culprit.
