Python Flask App Stuck in Waiting for localhost

Question

User2118594139 posted

I'm trying to run a flask app on a Server 2016 machine with IIS v10 and the httpplatformhander, here's my web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="PythonHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" requireAccess="Script" />
    </handlers>
    <httpPlatform processPath="C:\ProgramData\Anaconda3\python.exe" 
                  arguments="C:\Users\test\Documents\test_app\application.py" 
                  stdoutLogEnabled="true" 
                  stdoutLogFile="C:\Users\test\Documents\test_app\logs\acp.log" 
                  startupTimeLimit="60" 
                  processesPerApplication="16">
      <environmentVariables>
        <environmentVariable name="SERVER_PORT" value="%HTTP_PLATFORM_PORT%" />
      </environmentVariables>
    </httpPlatform>
  </system.webServer>
</configuration>

When I run `python application.py` in cmd it correctly opens my 'Hello, World!' app, but I can't seem to get it to work through the httpPlatformHandler.  I added IIS_IUSRS to the security options for my test_app folder and the anaconda3 folder.  Is there a location where I can see more detailed logs for diagnostics?

I have the same problem.

You can see error in log file. I got this:

AttributeError: 'NoneType' object has no attribute 'isatty': sys.stdin.isatty()

Traceback is in this line:

app.run() 

Does flask needs something additional except httpPlatformHandler to run on IIS?
