Erroe: failed to write to incoming websocket: ConnectionClosed

[wnz99]

Hi,

I'm having an issue with:

tunnelto 0.1.18

I'm trying to tunnel a wss connection however I'm getting an error. The same connection works with ngrock. The following are the two commands and the error logs:

ngrok http -region eu -hostname=### 172.28.1.3:8080
tunnelto --host 172.28.1.3 --subdomain ###--port 8080 -v

Logs:

I'm having the same issues with websocket connections when trying to run a code-server instance. The issue doesn't happen when issue ngrock or localtunnel alternatives.

[samuelstroschein]

Similar/same issue. I guess we are all using Hasura/GraphQL subscriptions over websockets? For unknown reasons, a websocket connection can not be established.

[wnz99]

Yes, it's Hasura subscriptions.

I'm also seeing similar issues when trying to expose a Guacamole console (https://guacamole.apache.org/). This works using localtunnel, but I preferred this implementation as (a) it is in Rust and (b) it has the potential to scale out.

I assume tunnelto is meant to support websockets?

[agrinman]

Hi -- we do support web sockets, though it seems like something is not working with hasura/guacamole. For example, this web socket example works just fine from my testing: https://github.com/gorilla/websocket/tree/master/examples/chat (note: adjust ws to wss in the html).

Can someone share a simple to replicate example?

[agrinman]

Hi: I rewrote a bit of the local tcp forwarding logic which I think might solve some of these more complex cases. Would someone be able to try a latest version to see if this fixes it for them?

cargo install tunnelto --force --version 0.1.19

(note 0.1.19 is not pushed to brew just yet) Thanks!

edit: it's really easy to get cargo if you don't have it, https://rustup.rs

[jcroucher]

0.1.19 fixed my issue loading wss urls

[jvalteren]

Hi @agrinman, I too have issues with use of WebSockets and would like to try this 0.1.19 version. I'm using Homebrew on macOS. However, I can't find version 0.1.19 anywhere on GitHub or in Homebrew. Any pointers as to how I can get this version or fix the issue in another way?

[CWSpear]

@jvalteren was having this issue and found this page as a result.

I'm on a Mac and was also using the Homebrew version.

cargo install tunnelto --force --version 0.1.19

(I have rust installed via Homebrew)

You do need to either uninstall the Homebrew version or make sure you're using the full path to the v0.1.19 one, e.g.:

/Users/cwspear/.cargo/bin/tunnelto --port 8080

All that said, I get a different error when using 0.1.19:

CONNECTION REFUSED
 ERROR tunnelto        > failed to open local tunnel
 ERROR tunnelto        > got data but no stream to send it to.
 ERROR tunnelto::local > failed to connect to local service: Connection refused (os error 61)

It doesn't work at all, so it's worse off than 0.1.18 :(

[jvalteren]

Thanks @CWSpear.

@agrinman what is the status of the rewritten local TCP forwarding logic? Any chance of pushing this to Homebrew?
