Generic error while opening channel

I have an Apache MINA client that tries to open a TCPForwardChannel, but on the server I see the following error

`{"time":"2025-12-03T13:17:19.280423473Z","level":"INFO","msg":"ssh: rejected: unknown reason 0 (IOException while opening channel: Generic error while opening channel: 30)"} `

Is there a way to find out what Channelhandler I should register to answer this case?

That's the MINA logs if it helps

```
