If you're having trouble connecting to TunnelBear, make sure the proper ports are opened on your network.
If you have access to your network/router settings, we always recommend making sure that the ports TunnelBear uses to operate aren't being blocked.
Windows, macOS, iOS, and Android all rely on the OpenVPN tunnelling protocol in order to connect. Windows and iOS also have a secondary protocol available called IKEv2/IPSec. These two protocols will need different ports opened in order to work:
OpenVPN needs port 443 (both TCP and UDP) to be unblocked. If a connection via port 443 is not successful, the application will try to connect using port 7011 (UDP only).
IKEv2/IPSec need UDP ports 500 and 4500 to be unblocked. Additionally, some routers have an "IPSec/IKEv2 Pass-Through" setting which opens the ports required for the VPN connection to operate.
