Google Account has suddenly got disconnected

Thank you for reaching the community forum. 

Our Endpoint does not have a feature to restrict Google sync. However, we have Application and web Control that can block access to applications or sites like google drive. For such a a case, this may need to be investigated locally by checking the event logs on the device to see what happened. 

Thank you for answering my question.

I've checked the windows logs on the device but there's nothing like Sophos caused logs.

However, when i compared windows logs with other device that syncs g drive correctly, i found there is one difference between them.

It is that the device in trouble with G Drive has a log described like 'Warning: no matching IRPs found for reply'.

Do you know what it means and whether it's caused by Sophos?

Thank you for your response. I did try checking, but based on our archive, I don't see such an event message being logged under our endpoint product. I did some further digging and found this event on Github, but there aren’t many details.

Thanks for your reply.

It seems like the trouble not caused by sophos, so i'll keep investigating from other perspective.
