I am trying to start HTTPS server on my localhost, but getting below error. I have opened cmd as an administrator.

Your windows firewall may block python from listening.
Additionaly, try adding a different port number higher than 1024 to the command line and see if it helps.

In a nutshell
Using Dockers Desktop Community Version 2.0.0.3 (31259) in macOS Mojave I have two containers:
Alpine
MySQL
From the Alpine docker I am not be able to access the mysql server instance that is running on MySQL docker.
In details
On Alpine I am running python2 and python package mysqlclient. This is the configuration file that I use in my python application to access the mysql databases:
dbtype MySQLdb
connect-args {"user":"abe","db":"abe","passwd":"123"}
upgrade
host docker-mysql
port 32779
When I launch python application I see that it is unable to connect to mysqld server, in fact I get following error log:
python -m Abe.abe --config abe-my.conf
Reconnecting after rollback error: (2002, "Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)")

How it could be "fixed"?
I saw that the access file is /run/mysqld/mysqld.sock and I found it in the mysql docker, I suppose it should not be a problem to be able to connect the two dockers so that they "see each other", but at the moment I have no idea.
I am trying to deploy a flask app on google cloud app engine. It runs smooth in my virtual environment locally but I get an 502 error running it in the cloud.
Now I am trying to debug my code on the cloud server, using debug mode and SSH into my instance. Using docker exec -it [ID] /bin/bash I am able to to access the root of my application. Now I upon running python app.py I get the following error:
* Serving Flask app "app" (lazy loading)
* Environment: production
WARNING: Do not use the development server in a production environment.

OSError: [Errno 98] Address already in use
I've been trying to kill those processes listed when I run:
ps -fA | grep python
However, this does not solve the problem of the address being in use. Also changing the port in the app.run() does not solve the issue for me.
I had a similar problem, it was caused by the Flask app also being run when the module was loaded, because I had
if __name__ == "__main__":
app.run()
at the bottom. Note that the recent requirement to name your sever file "main.py" could cause this bug to emerge.
I think the problem is that you don't need to specialize the port for cloud. Google Cloud finds the port to run your app on its own. So instead of app.run(port=8080) just write app.run()
While I was not able to figure out how to "free" the running address, I solved the problem by starting another flask process by running it on a different port like so:
flask run --port=80
This is what's printed on the console, If I start odoo with run instead of debug, it starts up normally, listens to 8069, and I can log in OK. Debug stopped working directly after the upgrade to 2016.1.2

I saw a hint about uninstalling gevent, and that worked for me. Strange because it stopped working after a intellij update. so:
apt-get purge python-gevent
pip uninstall gevent
I'm using python requests library to talk between two of my apps (django and ckan) inside Azure VM (clean ubuntu 12.04).
And very wired bug appears. It seems like request.post sent successfully, but on the middle of my code running I got 504 request timeout.
Apache2, Nginx and Gunicorn (only timeout appears) logs are clean. My CKAN app throws same error but with different ports:

As you can see port Is always different. One of my thoughts -- Azure has all ports closed unless you specify which one you want to open.
I have same codebase working alright locally.
By default, Azure linux VMs disable all ports except 22 to prevent inbound requests from internet. you can try to specify your Django app's port and configure the endpoint of the other VM with ckan.
Also, you can refer to https://github.com/Azure/azure-content/blob/master/articles/virtual-machines/virtual-machines-python-django-web-app-linux.md to deploy your django app on apache and bind it on 80 port on your VM.
I need to run a small flask server on Ubuntu and keep it up in case it crashes. I'm using supervisor to do that. It starts up fine the first time, but if it's restarted by supervisor (manually) the port is already occupied.
If the flask server is run from the command line it shuts down fine. The process does not seem to daemonize itself, which I understand can be an issue with supervisord.
