We have the same issue. Startet approximately a week ago. Our log file is identical with the one above.

We have tried to reinstall the GCP services and Google Chrome(latest version). Delete all printers and re-add them. We have about 40 printers connected to the print server, and neither of them work now since the past week.

Looking at https://developers.google.com/cloud-print/images/cloudprint2.png, Method A and B works, but not C. Method A was used on the same print server(Windows Server 2012).

This will be resolved soon. Fixed in issue :https://bugs.chromium.org/p/chromium/issues/detail?id=638516

I'm confused by Comment 4. The comment says it will "be resolved soon". The status says "WontFix"

We're trying to replace a Win2008 server and have unsuccessful using 2008r2 or 2012r2.

Been getting the same results as shown in Comment 1.

Thanks for your assistance.

Agree with Comment 5, it's a confusing answer.

Is there any ETA on the fix? I get permission issues when clicking the link in Comment 4.

In case this works for others. We have now several printers up and running again. Do the following and hope it works for you.

1. We downgraded Google Chrome on the print server to Version 51.0.2704.103 m.
2. We delete the User Data folder under %appdata% -> Local -> Chrome.
3. Deleted the folder for Google Cloud Print under %appdata% as well.
4. Disabled Google Update service in services.msc and in registry to make sure.

All the above steps might not be necessary, older version of Chrome should do the trick.

We will run on this version until the issue is resolved in a new version of Google Chrome.

This was done on a Windows Server 2012 using GCP services. 38 printers are now working again.
