what are Rider.Backend sending when I am coding

After I edited my code, the process "Rider.Backend" will send packages for about 10-50M every time. I noticed it on Activity Monitor of my Mac that usually it will send 2-4G of packages for 5 hours of coding


I just coding for 10 minutes, and it sent 81M 


JetBrains Rider 2023.2

macos 13.2


Hi Zhoujiazhiwork

This should be inner traffic between the backend and frontend parts of Rider. Let's double-check.
Please, run in console the following: 

lsof -n -i | grep -e LISTEN -e ESTABLISHED | grep -e rider -e dotnet. All connections related to Rider or dotnet should be something like this ->

This means that all connections are local and, indeed, traffic between Rider's backend and frontend. You can attach the result here if there is something strange.
I hope this helps!


Today I just updated the rider and found it's connecting to the 18.65.148.*
