You shouldn’t use bridges from any list you found on Google. Only use the bridges in [BridgesDB](https://bridges.torproject.org/), or use the Moat feature in Tor Browser.
To use Moat, click on the hamburger menu, go to Settings \> Connection \> Request a Bridge.
If you can not use Moat or BridgesDB, I can PM you bridges.

If you’re connecting from mainland China, you should use webtunnel ([https://bridges.torproject.org/options/](https://bridges.torproject.org/options/) \> select Webtunnel ) or a private obfs4 bridge from Tor frontdesk.
Bridges distributed by some BridgeDB’s distributors are enumerated and blocked by the GFW.

I think China knows how to block webtunnel bridges now. Did you try getting bridges from Moat or BridgesDB? Did you update Tor?
Do you have internet while connecting to Tor? Did you specify bridges in torrc?
@gus Do you think that China figured out how to detect and block webtunnel bridges?

that stack trace looks like the one from [tor#40895](https://gitlab.torproject.org/tpo/core/tor/-/issues/40895). This happens if the pluggable transport crashes in some cases. While tor shouldn’t crash when a PT crash, the underlying issue is that the PT crashes.
Does your apparmor profile allows for executing `/usr/bin/lyerbird`? Last i checked the defaultprovile only allows `/usr/bin/obfs4proxy`.

**Removed webtunnel and fixed “lyrebird” typo and other mistakes, complete config:**
```auto
ClientTransportPlugin meek_lite,obfs2,obfs3,obfs4,scramblesuit exec /usr/bin/obfs4proxy
ClientTransportPlugin webtunnel exec /usr/bin/webtunnel-client
ClientTransportPlugin meek_lite,webtunnel exec /usr/bin/lyrebird
```

Remove the webtunnel in the first line (`ClientTransportPlugin meek_lite,....`) as you have already set where the webtunnel client is in the next line, and obfs4proxy **does not** support webtunnel.
I won’t explain more (because I’m too lazy to type more lol), just copy/paste the fixed config to /etc/torrc and you should _maybe_ be good

How can TLS traffic pass through the firewall safely and effectively? Is this a problem? ? ? Otherwise it cannot be connected
