OSError: [WinError 10048] Only one usage of each socket address (protocol/networ k address/port) is normally permitted

Hello. There is a small problem with your script or with my knowledge of Python.
OSError: [WinError 10048] Only one usage of each socket address (protocol/networ
k address/port) is normally permitted
I use the standard example for ARS
It gives this error. Can you help me?

Hi,

It sounds like you already have something listening on that port. You might want to run netstat to show all listening UDP ports and disable/stop the offending service.

Hello again. I ran netstat first and found no services running on that port. Although I have a guess. I'm trying to use the in-place control radio utility MNIS. However, I don't think this is the problem. Another app is getting lrrp data fine

If you are using MNIS likely it is listening on the same port. The "OSError: [WinError 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted" error is an error your OS is kicking back because you can only listen on one address:port combination at once. Either this library is listening twice which I sorta doubt since I use it in my own apps, or there's already an app listening on your local computer with that port (which is likely, since you mentioned you run MNIS). Try on a totally blank computer/raspberry pi or a VM. Also, ARS is used for a lot of stuff with trbos, especially RMDP, so there may be more than just one app contending for use of that port.
