Server Error in Default Deployment of Azure Flask Web App

Question

I'm trying to deploy a Flask app within Azure, using the pre made template created by Azure.

I can't get a simple...

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello():
    return "Hello World!"

if __name__ == '__main__':
    app.run()

To do anything. To simplify further still, even the pre made deployment returns an error...

Clearly I'm misunderstanding something very fundamental here. Using FTP I can see the files that Azure is creating - sure does look like there should be a nice little demo site.

What am I doing wrong?

Cheers, Ben

Now it appears that it's working fine. Deploy a pre-built Flask app, click the link, up it pops just fine. I can't see where I was possibly going wrong - a rare occasion when the fault was not with me, I believe. — Ben Mayo

According to your description, I think the issue was caused by some incorrect configuration in the web.config & the Application Settings of your WebApp settings. Please try to refer to the blog to resolve it.

Meanwhile, I don't know what pre made template created by Azure you used. I tried to create a new Azure WebApp for Flask as below.

The file list in the wwwroot path in the Kudu tool or FTP shown as below.

Then, I modified the code views.py in the FlaskWebProject1 directory. And it works.

It seems to be more simple. Hope it helps.

I've been figthing the same issue for a while, I have only be able to workaround it by changing the pricing tier associated to the "service plan" to S2 Standard. If I try to use S1 Standard I run into the same issues.
