Hi Randy,
Thank you. 
I know precisely where you’re coming from - and yes, unfortunately. I could go into the details of the matlab-derived code that require that (or at least, without major re-architecture of the data flows) - but the bottomline is yes.
In addition, I can not even get streamlit to grab the public ip details from the windows machine, which in Linux is basically just setting it up in the config.toml.
My Linux instances run fine.
