I have 3 streamlit apps running - everything worked fine as of Tuesday. Today, all of them fail to upload a file (of any size) with Error: Request failed with status code 403. Any help would be appreciated. (In addition, link change is also a problem) Thank you!

Hey @svenstehle @lasinludwig @ADISH_A.P @alkadriishere @Anna_Sintsova Thanks for reporting the issue. We are aware of it and have reverted the URL change. This should work again, but if it’s still an issue, please let us know :slight_smile: Best, Charly

I’m getting the same error. Did you find a solution?

Yes! You need to add this on the config.tml file: [server] enableXsrfProtection = false enableCORS = false That worked for me. More on config files: Configuration - Streamlit Docs

Hello @Charly_Wargnier Streamlit Team, I am also facing the same issue , is there any bug in it, as per the previous comment you have mentioned regarding the url change and other thing. How do we get it resolved. Thanks in advance for help.

I have the same issue. Streamlit version 1.30.0 - only just upgraded today and it stopped working. I’m running this on localhost:8501

I have encountered the same issue AxiosError: Request failed with status code 403 for CSV uploads. This happened once I upgraded from 1.29 to 1.30. I have downgraded for now.
