I ran a simple flask web application on python on my localhost.
The web application is running on 127.0.0.1:8000. But I cannot access it from a remote machine in my network using myHostComputerIPaddress:8000.
My host is a windows machine. Please advise.
Your app.run() function must be app.run(host='0.0.0.0') in order to give access other devices on same network.

I have been banging my head against a wall trying to get my streamlit app deployed on an ec2 instance so I can share with others, however I am having trouble connecting to my streamlit app via the browser. I noticed that on my local machine I also have the same issue, when I run the streamlit app locally, I am able to access my streamlit app via local host:
http://127.0.0.1:8501/
However the "External URL" and "Network URL" do not work and the page infinitely loads and eventually times out. Here is the external url & network url given by streamlit when you run streamlit run app.py
Collecting usage statistics. To deactivate, set browser.gatherUsageStats to False.
You can now view your Streamlit app in your browser.
Network URL: http://<network_ip>:8501
External URL: http://<external_ip>:8501
I can confirm that I have allowed port 8501 TCP inbound traffic on my local windows machine as well as on the ec2 instance.
Here is my security group config:
EC2 Security Group
How do I make my streamlit application accessible via the given Network URL & External URL by streamlit and not just via localhost:8501?
Would appreciate anyone's advice who has deployed a streamlit web app on an EC2 instance!
I have checked that:
My ec2 instance is listening on TCP port 8501
That the streamlit service is running by running "ps aux | grep streamlit"
Restarting my instance
So this was a bit of a face-palm moment for me, the problem I was encountering was as a result of the internal firewall blocking connections to port 8501 on my corporate network.
I have a python application hosted by a node.js frontend. I am running that on a linux vm on Google Cloud virtual machine (GCP).
node appname runserver 8080 command starts local server within VM but I am wondering what would be step by step process to access it via a DNS from outside world.
Or if there is better approach to host python ML applications behind a web interface, then please suggest.
You need to use forever for this.
Forever will move the node process to the background and service will keep running in the background even if you log out of the server. And In order to access from outside point a DNS domain to this IP address of the machine and then Proxy Pass the request on port 80 to the port your service is running on.
Then you will be able to access it via domain name.
Look for ProxyPass directive in the Http server. That would work for you. :D
I deployed my flask rest api on IIS 8 to windows server 2012 r2. I followed this article. (https://medium.com/#bilalbayasut/deploying-python-web-app-flask-in-windows-server-iis-using-fastcgi-6c1873ae0ad8) I can browse the rest api on the local server but I can not browse the api from other computers on public internet. I can ping the public IP of the server without problem. There is no firewall rule that blocks the server. Would you please help me?
PS. I am trying to browse by the IP, 185.201.212.219. Is it related to this?
edit1: I will try this which is from flask documentation.
Externally Visible Server
If you run the server you will notice that the server is only accessible from your own computer, not from any other in the network. This is the default because in debugging mode a user of the application can execute arbitrary Python code on your computer.
If you have the debugger disabled or trust the users on your network, you can make the server publicly available simply by adding --host=0.0.0.0 to the command line:
flask run --host=0.0.0.0
This tells your operating system to listen on all public IPs.
edit2: Adding host parameter didn't work.
Is there any ideas?
Thanks in advance.
All ports except 80 was open. When I set port=80, all my troubles seem so far away :)
Im developing an app using flask framework in python, i wanted to host it on my pc for a few people to be able to visit it, similar to wamps put online feature but for flask instead, i dont want to deploy it to the cloud just yet. how can i do it.
Enable port forwarding on your router, start flask on the 0.0.0.0 address of your computer, set the forwarded port to be the one started on your laptop. This will now allow your LAN and calls to your ISP provided address to be directed to your laptop.
To clarify, LAN can do it without port forwarding in my experience.
I work on a project in which I need a python web server. This project is hosted on Amazon EC2 (ubuntu).
I have made two unsuccessful attempts so far:
run python -m SimpleHTTPServer 8080. It works if I launch a browser on the EC2 instance and head to localhost:8080 or <ec2-public-IP>:8080. However I can't access the server from a browser on a remote machine (using <ec2-public-IP>:8080).
create a python class which allows me to specify both the IP address and port to serve files. Same problem as 1.
There are several questions on SO concerning Python web server on EC2, but none seems to answer my question: what should I do in order to access the python web server remotely ?
One more point: I don't want to use a Python web framework (Django or anything else): I'll use the web server to build a kind of REST API, not for serving HTML content.
you should open the 8080 port and ip limitation in security croups, such as:
All TCP TCP 0 - 65535 0.0.0.0/0
the last item means this server will accept every request from any ip and port, you also
You passble need to IAM in AWS.
Aws set security permission that need to open up port so you only localhost links your webservice
aws link
