Also, if the error occurs only when connecting to a specific network, it is likely that this network is really unsafe and somehow manipulates security certificates, which is trying to warn Google Chrome.
Additionally (for Windows): This method is undesirable and potentially dangerous, but you can run Google Chrome with the iGnore-Certificate-Errors parameter so that it does not give messages about the security certificate certificates. You can, for example, add to the browser label parameters.
