I developed a python based application used Panel Holoviz, bokeh server inside Tornado web server. The business logic of application is once the server starts its calling some functions for creating machine learning models and use those models to predict and visualize the result using Panel widgets. This application is working perfectly in my local machine. I tried to deploy this application on Azure. Deployment is successful. But the application is taking long time to display and giving Application Error.
In the log its giving below details:

From the log what I came to know its not my code deployment issue, rather about the timeout issue. Could some one help me to find the issue (whether my finding is correct or not) and provide a solution.
In app.py, my launching file I gave
.show(host='0.0.0.0', port=8000).
