[Edit: More details added]

This small app is getting an 500 error when auth param is added 😔

```auto
import gradio as gr

def greet(name):
    return "Hello " + name + "!!"

demo = gr.Interface(fn=greet, inputs="text", outputs="text")
demo.launch(auth=("admin", "pass1234"))

```

More details from console:

> Traceback (most recent call last):

Note 1: It stopped working since Friday last week.  
Note 2: Tried ssr\_mode=False but no luck.

I’ve tried various things now. This is definitely a bug.

### Gradio 5.15.0 / 5.14.0 / 5.8.0

### Gradio 5.12.0

### Gradio 4.44.0

It works.

Just checked the issue with Gradio 5.17.1, it still gives an 500 error when auth param is added 😔

Does anyone have any news or tricks on how to launch the 5th Gradio version in Space?
