如果您的连接出现问题，一则错误信息会弹出，您可以选择“将 Tor 日志复制到剪切板上”选项。 然后粘贴 Tor 日志到文本文件或者其他文档格式中。

If you don't see this option and you have Tor Browser open, you can navigate to the hamburger menu ("≡"), then click on "Preferences", and finally on "Tor" in the side bar. 在此页面的底部，“查看 Tor 日志”字样旁边，点击“查看日志”按钮。

Alternatively, on GNU/Linux, to view the logs right in the terminal, navigate to the Tor Browser directory and launch the Tor Browser from the command line by running:

‪./start-tor-browser.desktop --verbose

or to save the logs to a file (default: tor-browser.log)

‪./start-tor-browser.desktop --log [file]

您应该能够在 Tor 日志中发现这些常见问题（请在 Tor 日志里寻找如下所示的错误）:

Common log error #1: Proxy connection failure

2017-10-29 09:23:40.800 [NOTICE] Opening Socks listener on 127.0.0.1:9150
2017-10-29 09:23:47.900 [NOTICE] Bootstrapped 5%: Connecting to directory server
2017-10-29 09:23:47.900 [NOTICE] Bootstrapped 10%: Finishing handshake with directory server
2017-10-29 09:24:08.900 [WARN] Proxy Client: unable to connect to xx..xxx..xxx.xx:xxxxx ("general SOCKS server failure")

如果您看见这些提示出现在您的日志里面，这意味着您连接 SOCKS 代理失败了。 如果您的网络连接需要设置 SOCKS 代理，请确认您代理服务器的信息正确。 如果您的系统不需要代理，或者您不敢肯定，请尝试直接连接 Tor 网络。

Common log error #2: Can’t reach guard relays

11/1/2017 21:11:43 PM.500 [NOTICE] Opening Socks listener on 127.0.0.1:9150
11/1/2017 21:11:44 PM.300 [NOTICE] Bootstrapped 80%: Connecting to the Tor network
11/1/2017 21:11:44 PM.300 [WARN] Failed to find node for hop 0 of our path. Discarding this circuit.
11/1/2017 21:11:44 PM.500 [NOTICE] Bootstrapped 85%: Finishing handshake with first hop
11/1/2017 21:11:45 PM.300 [WARN] Failed to find node for hop 0 of our path. Discarding this circuit.

如果您看见这些提示出现在您的日志里面，这意味着您的 Tor 无法连接到 Tor 网络中的第一个节点。 这可能意味着您处于有审查的网络中。

请尝试通过网桥连接，这应该能解决问题。

Common log error #3: Failed to complete TLS handshake

13-11-17 19:52:24.300 [NOTICE] Bootstrapped 10%: Finishing handshake with direc Tor y server 
13-11-17 19:53:49.300 [WARN] Problem bootstrapping. Stuck at 10%: Finishing handshake with directory server. (DONE; DONE; count 10; recommendation warn; host [host] at xxx.xxx.xxx.xx:xxx) 
13-11-17 19:53:49.300 [WARN] 10 connections have failed: 
13-11-17 19:53:49.300 [WARN]  9 connections died in state handshaking (TLS) with SSL state SSLv2/v3 read server hello A in HANDSHAKE 
13-11-17 19:53:49.300 [WARN]  1 connections died in state connect()ing with SSL state (No SSL object)

如果你在 Tor 日志里看见这句话，这意味着 Tor 和目录服务器无法完成 TLS 握手。 使用网桥可能会解决这个问题。

Common log error #4: Clock skew

19.11.2017 00:04:47.400 [NOTICE] Opening Socks listener on 127.0.0.1:9150 
19.11.2017 00:04:48.000 [NOTICE] Bootstrapped 5%: Connecting to direc Tor y server 
19.11.2017 00:04:48.200 [NOTICE] Bootstrapped 10%: Finishing handshake with directory server 
19.11.2017 00:04:48.800 [WARN] Received NETINFO cell with skewed time (OR:xxx.xx.x.xx:xxxx): It seems that our clock is behind by 1 days, 0 hours, 1 minutes, or that theirs is ahead. Tor requires an accurate clock to work: please check your time, timezone, and date settings.

如果您看见这些提示出现在您的日志里面，这意味着您的系统时间设置错误。 请确认您的时间设置是正确的，包括正确的时区。然后重新启动 Tor。
