I work freelance and use a number of different venues locally for my daily wifi connection. One of these venues offers free unlimited wifi which would be really useful for me, however I cannot get to the authentication landing page to login to their service (it's a local train station).
After connecting and opening a web browser, I get a “Your connection is not secure” message and some technical blurb about certificates (pdf of webpage attached).
I then click advanced and add exception, and all I get is a blank page with a giant “401” in the middle.
It’s obviously a security issue but I don’t know how to fix it. Have tried firefox, chrome and IE
Hope someone has an easy solution!
