If a visitor connects to the WiFi and misses the prompts to log in, when they try to launch a secure web page they may receive an SSL connection error, such as the examples below.
This occurs as most pages are 'secure' web pages (HTTPS or SSL), if the visitor is not logged in, the captive portal attempts to redirect any web traffic to the login page for the WiFi and you cannot redirect a secure page without one of the warnings below.
To avoid this, when a visitor connects to the WiFi a notification appears to prompt the visitor to log in and if this is followed it should prevent the warning message from appearing. Alternatively, as a workaround, if the visitor loads a non-secure site (e.g. neverssl.com) it should redirect to the login page.
If your visitors continue to have problems with SSL connection errors, please contact Support with examples of the issues from the visitors.
