You might be on a network that is blocking the Tor network, and so you should try using bridges. Some bridges are built in to Tor Browser and requires only a few steps to enable it. To use a pluggable transport, click "Configure Connection" when starting Tor Browser for the first time. Under the "Bridges" section, locate the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. From the menu, select whichever pluggable transport you'd like to use.

选择可插拔传输网桥之后,上滚并点击“连接”,保存设置。

Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar. In the "Bridges" section, locate the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. Choose whichever pluggable transport you'd like to use from the menu. Your settings will automatically be saved once you close the tab.

如果您需要其他的桥接,你可以从桥接网站 上查询。 关于网桥的更多信息请参阅 Tor 浏览器用户手册
