Deployed Streamlit app fails to initiate WebSocket connection

WebSocket error in deployed Streamlit app. Try these configs:

server { listen 8601; location /ws { proxy_pass http://127.0.0.1:8601; } }

[config]
port=8602
cors=false
headless=true

I encountered a similar WebSocket connection issue during a deployment, and my solution centered on careful configuration alignment. I reviewed and ensured that the ports specified in the Streamlit and reverse-proxy configurations were consistent. Additionally, I confirmed that network settings such as firewall and binding addresses did not block the communication channels. After methodically verifying that all deployment parameters matched those in my development settings, the connection problem was resolved. This approach reinforced the need for consistency across the various configuration files and network policies.

hey all, i tried a simmilar fix with changed websokcet paths and it helped a bit. anyone had to use https too? maybe trying ssl certs might fix the issue? anyone expermiented with that coniguraiton? lookng forward to your ideas

hey sophia, i wonder if a slight version mismatch might be causin the webscket snag? i played around with some deployment params and noticed logs sometimes hint at low-level issues. have you tried advanced logging or got other config tweaks that helped?

hey sophia, i had a similar problem. i ended up tinkering with the ws port and turned off cors, plus cleared cache. not a miracle cure but seemed to ease the conneciton issue
