I'm noticing that on the login page, a request is made to https://client.openvpn.net:946/detect.p ... =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 https://productforums.google.com/forum/ ... 19ZxwjaCjw and https://www.chromestatus.com/features/4981025180483584 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 client.openvpn.net (for example, passwords, messages, or credit cards).
Clicking "Advanced" adds the following message:
This server could not prove that it is client.openvpn.net; its security certificate does not specify Subject Alternative Names. This may be caused by a misconfiguration or an attacker intercepting your connection.
