Thank you so much for the reply.
Yes, I am running ubuntu in Windows server 2019.
Have you tried running from other ports to debug whether you can run a Streamlit app from that configuration at all?
Yes, I have tried other ports which worked fine, except port 443 and 80.
I got the Permission denied. Could you show me how to run streamlit with sudo? Thanks a lot!
Please refer Permission denied in ec2 port 80 - #6 by Steve_Chen
The reason I gone through these was because the web site I created using Streamlit is insecure! I have launched the web site but no one was willing to test because of it (insecure). I need to use https to make it a secure web site. Am I on the right track?
