If Tor VPN is unable to connect, you might see a error message:

To troubleshoot, try each of the following:

Check Android settings

• Ensure you do not have another VPN app running. Android does not permit the use of multiple VPN applications at the same time.

• Please ensure a network firewall application is not running. Firewall application usually use a VPN connection and if running, will prohibit Tor VPN from making any connections.

Check on the Tor VPN application

Taking a look at the Tor VPN logs can be helpful in diagnosing the issue. To fetch the Tor VPN logs:

• Tap on "View Tor logs" from the error message or from the "Connect" screen.
• Tap on "Configure".
• Scroll to the "Advanced" section of the Tor VPN settings.
• Tap on "Tor logs".

00:00:00:00 W/onionmasq: tor_chanmgr::transport::default: Connection to [scrubbed] failed: error: Network is unreachable (os error 101)

Error #2: Check if Tor is censored in your network.

In this case, trying one of the censorship circumvention methods might work.
