While using the Wi-fi at work I have tried every single “free” VPN that I can find in the Play Store with no success. They all just try to connect but never actually connect. Hotspotshield is the ONLY free VPN I can connect to and it does it in a matter of seconds (as it should be with all VPNs?) but after hitting the daily limit…well I want to switch to a different one.
The wifi here is very secure, how does hotspotshield get through? Any others I can try with the same success?
Port you are connecting to with hotspotshield is not blocked (ex: 443) while other free ones use 1134 etc and is likely blocked.
Your work wifi is able to detect a vpn tunnel connection attempt (ex: openvpn) and blocks it [I have no idea if this can be done], maybe hotspotshield is using a special connection type.
maybe your work wifi has a block on IP’s that the free vpns use
I am not a network tech but that may lead you in the right direction.
