Wifi selected is strong - but site blocked so cannot login
I am at a hotel and need to get on to their wifi (big hotel chain, not a small one). The wifi is successfully selected and the signal is full. When I try to login to get get access, I get the red stop sign with the "X" in the middle and then a message that says "Site blocked. This site has been identified as a security risk and has been blocked to protect your privacy". When I expand for details, I get the following certificate info " *.aws.opennetworkexchange.net".. then "Amazon" then "Amazon Root CA 1" then "Starfield Services Root Certificate". I searched the internet for hours (on my MAC-which successfully was able to login into the hotel wifi) and cannot find a solution. I am signed on to my computer writing this now as I cannot get internet access on my BB Passport. So, any solution will have to be without internet access. Please help as I am in this hotel for many days at a conference and would like to be able to login to the hotel wifi so I can get internet! Thanks
