Does Azure Function App supports socket io with python?

Question

I have created a python socket io server in python and started with flask app. It's working fine on local machine whenever a client hits the flask server it makes the initial handshake with socket io server. When I deployed the same on Azure Function app the deployment was successful and other flask endpoint is also working fine. But when I run any client initially connection established but after few seconds it disconnects and try reconnecting.

Please let me know if there is any solution. Or weather it is possible to use socket io with Azure Function App or I have to move to Ec2 machine.
