Hello,
I have docker container with NGINX and with that configuration
map $http_upgrade $connection_upgrade {
default upgrade;
‘’ close;
}
server {
listen 80;
listen 443 ssl;
server_name server_name.com;
ssl_certificate /etc/nginx/ssl/fullchain.pem;
ssl_certificate_key /etc/nginx/ssl/privkey.pem;
location / {
proxy_pass http://192.168.50.140:8501;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
location /_stcore/stream {
proxy_pass http://192.168.50.140:8501/_stcore/stream;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_read_timeout 86400;
}
}
On my server I have a basic application streamlit. For testing connection I leave just that
import streamlit as st
def main():
st.title("Basic Streamlit App")
st.write("This is a basic Streamlit app for testing purposes.")
# Add more Streamlit components as needed
st.write("Feel free to modify this code and add more components.")
if __name__ == "__main__":
main()
I set version 1.23.0 but with latest version I had the same issue.
Connection via http is working.
I read guide and went through the solutions but nothing helped
@Elshan_Gadimov
So, My location block in nginx conf file was
location /_stcore/streamstream {
}
instead of
location /_stcore/stream {
}
That extra “stream” was the typo.
also this article
I added necessary configuration based on thathttps://nginx.org/en/docs/http/websocket.html
I added that one as well /_stcore/stream
Please help me. Maybe I missed some detailes. Thank you.

Getting same error:
working on http
not working on https
Here is my nginx config file:
server {
server_name my_domain;
listen [::]:443 ssl; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/my_domain/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/my_domain/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
keepalive_timeout 5;
location / {
proxy_pass http://127.0.0.1:8501/;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
}
location /_stcore/stream {

proxy_read_timeout 86400;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
server { # managed by Certbot
if ($host = my_domain) { # managed by Certbot
return 301 https://$host$request_uri; # managed by Certbot
} # managed by Certbot
listen 80; # managed by Certbot
listen [::]:80; # managed by Certbot
server_name my_domain; # managed by Certbot
return 404; # managed by Certbot
} # managed by Certbot
And my config.toml:
[server]
port = 8501
serverPort = 443
serverAddress = "my_domain"
enableCORS = false
enableXsrfProtection = false
gatherUsageStats = false
And I launch my streamlit app with this command:
$ streamlit run app.py
Thanks for bringing support!

OK it’s solved !
I had both services opened on port 8501
I did proceed as follows:
push streamlit to port 8502
kept nginx on port 8501

location ^~ /healthz {

}
}
CONFIG.TOML
[server]
port = 8502
enableCORS = false
enableXsrfProtection = false
headless = true
And think about restarting both services:
$ streamlit run app.py
$ sudo service nginx restart
