Recently upgraded some sites to 5.9.2. Clients started complaining they are unable to login in the captive portal.
Captive portals being used are hosted on the APs. Some are using customized, some are running external pages.
Looks like it's a problem only with certain devices, mostly newer Androids. Clients are getting either timeouts or SSL protocol errors during redirection.
I'm seeing clients captive portal assistants trying to open http://126.96.36.199:880
which now gets redirected to https://188.8.131.52:880
by CloudFlare and that explains the SSL error and also the timeouts because there's nothing at that location.
Anyhow, did not see anything in the release notes but did notice article https://extremeportal.force.com/ExtrArticleDetail?n=000034307
I've set a virtual hostname for all captive portals which solves the issue, but do we need to change some setting for the new 184.108.40.206 redirection IP address to take effect? Recreate the captive portal?
