I found the solution on how to use the custom domain name. You can configure your apps to port 80 instead of using the streamlit default port 8051.


modify .streamlit\config.toml
[server]
headless = true
port = 80
[browser]
serverAddress = “www.name.cm”


Run command: streamlit run your_script.py --server.port 80


Open web www.name.cm
