Hi community! I’m writing a streamlit app and using the st.file_uploader() to upload video files (mp4 or mpeg). When I try to upload files larger than 100mb, I get a network error. This happens both when the app is run locally and when it’s run remotely. I already tried to increase the maxUploadSi…

Hi @evah , welcome to the community! I don’t know for certain, but your issue sounds suspiciously like this GitHub issue: Transfer large websocket messages as a sequence of smaller chunks opened 05:06AM - 15 Oct 19 UTC (UTC) …

unfortunately my streamlit version already 0.59.0, i already tried to re-install streamlit but still got an error. i tried to upload file more than 200mb (without server.maxUploadSize) and got different warning (a normal one i guess). the warning i got from uploading file between 100mb - 200mb and l…

Hi @bruhtus and @evah , thanks for your patience.

I will send a note to our engineers and see if they can identify what the issue is. GitHub issue…

Hi @evah @bruhtus , we have just released a fix for this in 0.62. Please upgrade and take a look. If you are still encountering any issues, please let us know.
