This could be the SSL captive portal issue with any vendor.  When you try to load for example https://www.google.com and get held in captive portal, you will be redirected to a different server while your browser things you are still going to google and therefore get a SSL error.  You can test this theory but try to go to http://neverssl.com or any plain http site (not https) and see if you still get the error.

It is about SSL on Google side, you may search for HTTP vs HTTPS to learn more. :)
