Hi @aidlml — and welcome to the forum! :wave:

I found similar issues that might help:

It looks like Windows (or some other software) is blocking socket access to the provided port.
Please let me know if the issue persists!

I tried all possible things but unable to use streamlit on windows machine. :slightly_frowning_face:

Hi @aidlml,

Can you say, specifically, what you’ve tried so far?

Faced the same issue and I was able to solve it by changing the default port:

streamlit run app_name.py --server.port 5998

on windows machine with

streamlit==0.65.1

Try in the following order

netstat -a -o -n “”" Find #### “”"
taskkill /F /PID ####
pip install streamlit==0.65.1
streamlit run Filename.py --server.port ####

This works

Did your issue got resolved?

Hi! It seem we’ve encountered same problem “PermissionError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions” when running streamlit code via anaconda environtment terminal. It took me to resolve the issue more than 3 days :-(, still not bad. But here’s you need to do to resolve the issue:
The default server port of the streamlit is 8501, but there are cases that the 8501 server port is already in used in your system. You may try to verify it using this CMD Code: netstat -a
then wait until the process is completed. Once conpleted, enter this code again: netstat -na | find “8501”
If there the queries will find the 8501 port, then it means it is already in used.
Solution: Chose different port like 8502, 8503, … an so on. To do this, simply add the --server.port 8502 in your code.
Example: From
streamlit run “C:\USER\RAI\app.py”
Use the code: streamlit run --server.port 8502 “C:\USER\RAI\app.py”

Hope this will work.
