I have a streamlit app running on 8501 port on localhost, I have configured a apache reverse proxy to expose this app outside on 443 port, Here’s the configuration for that:

<VirtualHost *:443>
     ServerName streamlit-app-test.domain.com
     DocumentRoot "/opt/lampp/htdocs"
     <Directory "/opt/lampp/apache2/htdocs">
       Options Indexes FollowSymLinks
       AllowOverride All
       Order allow,deny
       Allow from all
     </Directory>
     Header set Access-Control-Allow-Origin "*"
     Header set Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept, Authorization, sap-contextid-accept, MaxDataServiceVersion, x-csrf-token, sap-cancel-on-close, DataServiceVersion,x-sap-cid,access-control-allow-origin,access-control-allow-credentials, Host, X-Real-IP, X-Forwarded-For, X-Forwarded-Proto "
     Header set Access-Control-Allow-Credentials "true"
     Header set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT, PATCH"
     Header set Access-Control-Expose-Headers "x-csrf-token, x-sap-cid, content-type, authorization, accept, x-request-with"
     ProxyPreserveHost On
     ProxyPass / http://localhost:8501/
     ProxyPassReverse / http://localhost:8501/
    
     ProxyPass /ws/ ws://localhost:8501/
     ProxyPassReverse /ws/ http://localhost:8501/
    
     ErrorLog /opt/lampp/logs/error_log_test
     CustomLog /opt/lampp/logs/access_log_test combined
</VirtualHost>

When I load it locally like http://localhost:8501/ but when I try to browse it through https://streamlit-app-test.domain.com/ I get the following error

main.1661a802.js:2 WebSocket connection to 'wss://streamlit-app-test.domain.com/_stcore/stream' failed: 

I see that in the sources tab of developer tools in chrome cdn.segment.com is present while loading it through http://localhost:8501/ but not through https://streamlit-app-test.domain.com/

I have also enabled mod_proxy_wstunnel by adding following line in /opt/lampp/etc/httpd.conf file

LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so

I have also enabled CORS in streamlit but adding following line to /.streamlit/config.toml file but not sure how to verify if CORS is enabled or not

[theme]
base="dark"

enableCORS = true

What am I missing?
