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!
Exactly the same problem with me. Attached is the screenshot of the file upload button after I tried uploading a file.
Is this error related to the URL change?
I’m also facing the same problem from today.
Is this happening due to the link change? Can anyone advise a solution to this ?
Same problem here.
After some googling I tried putting these in my config.toml:
[server]
maxUploadSize=200
enableXsrfProtection=false
…didn’t work.
Same for me, thanks for opening this issue. My app also has the same problem. Runs fine locally, but upload fails on streamlit cloud.
Setting
[server]
enableCORS = false
enableXsrfProtection = false
enableWebsocketCompression = false
Does not help

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

Hello @Charly_Wargnier!
I’m having the same issue today. Maybe I’m doing something different from the guys? I don’t know. Can you help?
Hi @jgbalves
Apologies for the slight delay in answering your question. For some reason, your post seemed to have slipped through the net.
I suspect this was a temporary issue which should now be fixed. Would you mind retrying and let us know, please?
If the issue persists, I shall raise a ticket to the Devs asap.
Best wishes,
Charly
Hello @Charly_Wargnier !
All sorted, my url was masking Heroku, so the csrf was catching me . Now it just redirects to the Heroku url. Thanks for the help!
