asp.net core app deployed on iis meets 500 internal server error

Change stdoutLogEnabled=”false” to true and then check the logs at stdoutLogFile=”.\logs\stdout”. The error(s) there might tell you something.

Check that you set up right Environment Name using ASPNETCORE_ENVIRONMENT environment variable as so use correct settings like connection string. On your machine by default you have “Development” environment.

You may use Error Handling middlewares for showing exceptions like

app.UseDeveloperExceptionPage();
