If you're having trouble connecting to TunnelBear, make sure the proper ports are opened.
If you have access to your network/router settings, we always recommend making sure that the ports TunnelBear uses to operate aren't blocked.
Android uses OpenVPN as its tunneling protocol. Windows, macOS and iOS have two tunnelling protocols available for the latest versions of the app, OpenVPN and IKEv2/IPSec. These protocols will need different ports opened in order to work:
1. 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). If you're using the GhostBear feature, Windows uses port 3389, all other platforms use port 6418 (both TCP and UDP).
2. IKEv2/IPSec needs 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.
