The Group for Reporting and Discussing Bugs

Steam has been getting a lot of updates recently, and I would like to report that there are no major bugs in Garry's Mod at this time, but after an update, to keep everyone with the same Steam model to prevent counterfeit accounts, Garry's Mod will kick players after a scan of their Steam browser. This is normal. You may get a message that says, "Steam Auth. Ticket Has Been Cancelled," or, "Client Timed Out." These mean there has been an update to Steam and it should be updated as soon as possible. Don't think VAC has banned you or that GMod is broken, because that is not the case.
