When trying to go to the highlighted discussion Ask Me Anything 12th July: guest's introduction and questions my chromium browser gives an error message,

Your connection is not private Attackers might be trying to steal your information from meta.physics.stackexchange.com (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID''

This server could not prove that it is meta.physics.stackexchange.com; its security certificate is from *.stackexchange.com. This may be caused by a misconfiguration or an attacker intercepting your connection.''

Something similar on firefox.

What's wrong?

You are trying to access the meta site over HTTPS. This is not supported yet, because it's impossible to configure a certificate for all (150+ of them) meta.*.stackexchange.com sites.

So, to make things work, SE developers will switch the meta URLs to *.meta.stackexchange.com, for example this site will be http://physics.meta.stackexchange.com. This is being worked on. Until then, either use HTTP for accessing the meta, or ignore the warning about invalid certificate.

    $\begingroup$ But the link (on the right, ''UPCOMING EVENTS'') contains https:// hence pretends to be secure. So that link should be changed! $\endgroup$ Jul 12, 2016 at 15:52
