You cannot access the Internet from Tails until you are connected to Tor. For
example, *Tor Browser* displays the error message <span class="code">P`The proxy
server is refusing connections</span>` until you are connected to Tor.

You cannot access the Internet from Tails until you are connected to Tor. For example, *Tor Browser* displays the error message `The proxy server is refusing connections` until you are connected to Tor.

<p>Because Tor routes your Internet traffic through 3 relays
before reaching its destination, the
connection is slower than when you are not using Tor.</p>

<p>See our documentation on
[[why Tor is slow|doc/anonymous_internet/tor/slow]].</p>

When you choose this option:

First, Tails synchronizes the clock of the computer automatically, because a correct time is needed to be able to connect to the Tor network.

Tails learns the current time by connecting to the captive portal detection
service of [Fedora](https://getfedora.org/), which is used by most Linux
distributions. This connection does not go through the Tor network and is an
exception to our policy of only making Internet connections through the Tor
network.

<p>You can learn more about our security assessment of this time
synchronization in our [[design documentation about non-Tor
traffic|contribute/design/Tor_enforcement#non-tor-traffic]].</p>

If you choose instead to [[hide that you are connecting to Tor|tor#hiding]],
you might have to fix the computer clock manually.

If Tails fails to synchronize the clock because you have to sign in to the network using a captive portal, an error screen is displayed that helps you do so.

If public relays and default bridges don't work, Tails asks you to configure a **custom bridges**, if connecting using the default bridges fails.

If public relays and default bridges don't work, Tails asks you to configure a **custom bridge**, if connecting using the default bridges fails.

When you choose this option, Tails will only connect to Tor after you configure a custom Tor bridges. Bridges are secret Tor relays that hide that you are connecting to Tor.
