What happened?

When I run the command qwen, I encounter the error Failed to login. Message: Failed to initialize Qwen: Qwen OAuth authentication failed.

What did you expect to happen?

Qwen should be properly initialized.

Client information

Client Information

Run qwen to enter the interactive CLI, then run the /about command.

$ qwen /about
# paste output here

I can't enter the interactive CLI.

Login information

None

Anything else we need to know?

Qwen supports two authentication methods: Qwen OAuth and OpenAI. I can successfully authenticate using the OpenAI method and use the Qwen CLI without issues.
