Aws address does not connect

🎈 Using Streamlit
,
1

I have an application on an aws ec2 virtual machine. if I connect to streamlit using the ip address http://18.222.39.57:8501/ it works fine. however, if I use the server name ec2-18-222-39-57.us-east-2.compute.amazonaws.com:8501, the app starts but stalls at the “please wait” state. So the server is found, but streamlit does not start correctly. Is there anything I need to consider to use the server name instead of the address?

Hey @godot63,

It looks like a CORS problem, did you try configuring browser.serverAddress with ec2-18-222-39-57.us-east-2.compute.amazonaws.com ? or even disabling CORS using server.enableCORS ?

sorry for the long wait @arraydude, I got sidetracked with other stuff. Now the app is ready but I have not solved my problem yet. I was able to change the setting on the localhost in the config.toml file. and it shows up when I run streamlit config show.

[server]
port = 8501
enableCORS = false

However I need to apply it on my AWS AMI machine. Where do I find this file?

No worries about it @godot63, The config.toml file should be always located at ~/.streamlit/ , but you could also pass the configs through the CLI as it is shown here.

So for instance it would be like this:

streamlit run examples/example.py --server.port 8501 --server.enableCORS False

If you want to check all the options:

streamlit run --help

or this, to check the applied ones

streamlit config show
