When I turn on the smartbear secure tunnel and only selecting: Accept all SSL certificates - our testing website is loaded but when I tried to login to the testing website I get stuck on the loading page and seam to not be able to get any further.
When I try turning on the smartbear secure tunnel select both: Accept all SSL Certificates and Bypass tunnel for public URLs - when I select run test on mobile device for live testing - the simulator is only displays in green and doesn't load anything. Some of my team members are getting Loading URL but then are not able to get any further.
I am not sure... Maybe this is something specific to your tested application...
