Keep hitting 500 Internal server error when trying to launch gradio app in Spaces
I’m trying to implement basic username/password authentication in a Gradio app. It works locally but fails in HF Space.# Basic auth configuration
app.launch(
    auth=(username, password), # username/password from env vars
    show_api=False
)Environment variables are properly set in Space as secrets (APP_USER, APP_PSWD).This is the error I am getting:Error: Login credentials are required to access this space.
ValueError: When localhost is not accessible, a shareable link must be created. Please set share=True or check your proxy settings to allow access to localhost.What’s the correct way to implement basic auth in a Gradio app on HF Spaces?Link to my space:Transcribe4myfriend - a Hugging Face Space by lucharo

From the error message, it seems that it should work just by passingshare=Truein.launch(), but in the first place, a normal Space works withshare=Falseor the default without any options.I don’t know why it needs to be set…github.com/gradio-app/gradioFailed to access localhost when set to share=False under WSL2opened08:34AM - 19 Mar 23 UTCclosed09:52PM - 28 Apr 23 UTCStarlentobugpending clarification### Describe the bug

gradio == 3.18.0, Under WSL2:
set share=False, it outputs…`ValueError: When localhost is not accessible, a shareable link must be created. Please set share=True.`.
But set share=True. It successfully runs on `127.0.0.1:7860` and `.gradio.live`.
I also checked `jupyter notebook` with the same environment, it works.

Mmmm, thank you for the response, I changed it toshare = Trueand I get this:/usr/local/lib/python3.10/site-packages/gradio/blocks.py:2596: UserWarning: Setting share=True is not supported on Hugging Face Spaces

I think it’s safe to ignore that warning. It doesn’t interfere with the operation. In fact, it seems to be in a running state.The problem is the 500 error that is currently occurring, but this is a little unusual. There is a possibility that it is similar to the Tonic issue below. I hope it’s a problem that can be dealt with by the author’s side alone…This error has occurred twice, and the last time it was due to a faulty network cluster. This time, the cause is still unknown.huggingface.co@Tonic on Hugging Face: "🙋🏻‍♂️hey there folks,

Hi HF-ers,I also encountered a 500 Internal server error code when I passed:demo.queue().launch(auth = custom_auth, share = True)See:huggingface.coTrial Login - a Hugging Face Space by patrickmakDiscover amazing ML apps made by the communityI’m trying to build the web app with simple auth using Gradio 5.8.0 which works well locally or on Colab.Is this the same issue that you guys discussed above?No updates on this 500 issue?Thanks!

I think your problem is called theTonic’s 500 error. By the way, there’s nothing wrong with Tonic. In short, it’s a bug caused by theServer Side Rendering (SSR)used in Gradio 5. In many cases, you can get around it by settingssr_mode=False. Alternatively, you can revert to Gradio 4.44.1 or earlier.#demo.launch(share=True, auth=("username", "password"))
demo.launch(share=True, auth=("username", "password"), ssr_mode=False)DiscordDiscord - Group Chat That’s All Fun & GamesDiscord is great for playing games and chilling with friends, or even building a worldwide community. Customize your own space to talk, play, and hang out.
