Streamlit + Sticky Sessions

Hey guys, just wondering if anyone has successfully deployed a streamlit app that leverages the upload functionality. Reading the streamlit forums, this requires Sticky Sessions to be enabled on the cloud provider and I am trying to avoid putting a proxy in the path to just handle the session cookies. (as per the fly-replay solution).

My app uses the file_uploader, and it works fine most of the time. But sometimes I get a AxiosError: 403. In previous weeks, just waiting a minute before trying again made the problem go away. But last night, when I was trying to demo the app for someone, I ran into this problem and it didn’t go away at all. But now today, on another computer, it’s working fine. I don’t understand why this comes up intermittently or what I can do about it. Advice is most welcome!
