Deployment

I have spent some time on the issue and eventually found a solution to the problem (inspired from the solution found here. You may try to follow the below steps and see if it helps:

(Indeed, I have my Raspberry Pi reinstalled earlier today due to some other technical issues and hence I am sure that the below steps work well in a newly installed Debian 10 OS that is hosted with an Apache2 server :smiley:)

  1. Create a config.toml under ~/. streamlit folder:

    cd ~/. streamlit
    sudo nano config.toml

  2. Type the below in the config.toml and save it:

    [server]
    port = 8501
    enableCORS = false

  3. Ensure that the below a2enmods are enabled:

    sudo a2enmod rewrite
    sudo a2enmod proxy
    sudo a2enmod proxy_http
    sudo a2enmod proxy_wstunnel

  4. Navigate/ Create an Apache .conf file and type the below:
    (Replace the text with your domain in the <Your Domain/ Sub-domain> below)

    <VirtualHost :80>
    ServerName <Your Domain/ Sub-domain>
    RewriteEngine On
    RewriteCond %{HTTP:Upgrade} =websocket
    RewriteRule /(.    ) ws://localhost:8501/$1 [P]
    RewriteCond %{HTTP:Upgrade} !=websocket
    RewriteRule /(.*) http://localhost:8501/$1 [P]
    ProxyPassReverse / http://localhost:8501
    </VirtualHost>

  5. sudo a2ensite the config file created in the last step and then sudo service apache2 restart should then be able to solve the “Keep Connecting” issue.
