Hi,
Welcome to the RStudio community!
I must say the 127.0.0.1 issue happens to me as well from time to time, but not as consistently as in your case and there are hardly ever non-response state. I'm no expert in this, but it seems it's an issue that pops up from time to time for many people, and there's not clear one solution for it.
However, I found this great recent RStudio blog post that might help you out!
Hope this helps,
PJ
