If you have exhausted general troubleshooting steps, it's possible that your connection to Tor is censored.
In that case, connecting with one of the built-in censorship circumvention methods in Tor Browser can help.
Connection Assist can automatically choose one for you using your location.
If Connection Assist is unable to facilitate the connection to Tor, you can configure Tor Browser to use one of the built-in circumvention methods manually.
To use bridges and access other censorship circumvention related settings, click "Configure Connection" when starting Tor Browser for the first time.
In the "Bridges" section, locate the option "Choose from one of Tor Browser's built-in bridges" and click on the "Select a built-In bridge" option.
From the menu, select a censorship circumvention method.

In the "Bridges" section, locate the option "Choose from one of Tor Browser's built-in bridges" and click on the "Select a built-In bridge" option.
