Hi, please just run all cells and only try to hit the URL from ngrok that's like so: http://377f47dc6ed1.ngrok.io
The IP of the colaboratory instance will not be exposed so you cannot hit those IPs.

Thank you, I'll try that! Could I bother you again if it doesn't work? (If you don't mind, of course )

You can always leave a comment and I'll get to it when I can. Please try to be verbose with the steps you took and the errors you're seeing, maybe even a link to a Colaboratory notebook that you're running it in so the errors can be reproduced.

Wait. If I understand right. If I execute this code may I can use Streamlit on Google Colab? Is it?
Its the first time that I'll use Streamlit, as Data Scientist I can use matplotlib, pandas, etc, but seems very nice plot in Streamlit.

If you can help me with that, please I follow u on Instagram.

I took a quick look. I think you can make prototypes and develop with Streamlit on Colaboratory, but you wouldn't want to make that your production server as Colaboratory has a relatively short timeout (only about 12 hours). You can find more on how Streamlit could maybe fit with your projects here: https://www.streamlit.io/

Thanks guys! It can work in colab!
But i see some difference between run in colab and run in local.
When i run streamlit hello in local, I choose Animation Demo and run it. The Animation move move and move ...
But i run streamlit hello in colab like your code, I choose Animation Demo however the Animation don't move. only stand still

Hey! I am getting this error when I try opening "https://2f10-35-196-239-11.ngrok.io/" this link. Please help.

The connection to https://2f10-35-196-239-11.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:80.

Make sure that a web service is running on localhost:80 and that it is a valid address.

The error encountered was: dial tcp 127.0.0.1:80: connect: connection refused

I have the same problem as you. Did you solve it?@Aishwary-Rawal
I use VPN when I am using Colab. Is the problem related to this?

I could not use this way. the localhost refused. thus, i find the other way to solve it
npx create localtunnel and show the url to check in the browse

!streamlit run app.py & npx localtunnel --p 8501
