I have had lots of problems with Chrome and Gmail in the past, especially when the earlier releases seemed to be buggy for proxies. But this error message takes the top prize! For the record, I was not using a proxy, and am on a direct connection to a Tier 1 ISP.
For those who are not inclined to click on the pic, the error states "It seems there is a problem. Please try using Gmail with a supported browser".
