Your startup.cs has some runtime code that isn't playing nice with Azure. Force the developer friendly exception page to render by moving app.UseDeveloperExceptionPage(); to the beginning of the Configure(...). Publish updated code to Azure, reload home page and exception will now be helpful.

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
     {
          app.UseDeveloperExceptionPage();
      ...
     }
