SignalR Core app deployed to Azure doesn't work over https

Question

I've created a simple web app with SignalR Core and deployed it into Azure, and enabled websockets for app service.

But after that when I try to access it using https:// it returns HTTP ERROR 500.

Any idea what is wrong? Do I need to set anything else in settings to make it work over https?

Please make sure your SignalR app could run without any error before publishing it to Azure website. I have a sample app that works fine on local and Azure, please refer to it.

    app.UseMvc(routes =>

Besides, this article is about “Getting started with SignalR Core”, please refer to it.

Thank you for the answer. It works locally and it was working in Azure before I switched websockets on in Azure. Probably I need to play around more to get more details. — KonstantinF, Apr 13 '17 at 11:07
``It works locally and it was working in Azure before I switched websockets on in Azure`` Please try to publish your application to a new Azure web site and test if it works. — Fei Han, Apr 14 '17 at 08:29
