I'm noticing that on the login page, a request is made to ... =timestamp. However on recent versions of Chrome (58+), this is blocked because the Certificate in use by that server does not have a Subject Alternative Name. See ... 19ZxwjaCjw and for some context.

When attempting to browse directly to the URL, Chrome presents the following error message:
Your connection is not private

Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards).


Clicking "Advanced" adds the following message:
This server could not prove that it is; its security certificate does not specify Subject Alternative Names. This may be caused by a misconfiguration or an attacker intercepting your connection.

It's unfortunately a known problem caused by browsers changing the way certificates are accepted. It's being worked by basically changing everything about how the communication between client and server works. In the meantime, just use the tray icon to make a connection.
