I'm trying to setup Copilot in RStudio. When I do the Github Copilot sign in after I click on the url given in "navigate to" and enter the code Github says " Congratulations, you're all set! Your device is now connected." But the dialog hangs in RStudio with the little "Authenticating" alert stuck on. Done it twice now.
I'm not sure what's problem in this situation since I didn't met it. But if I'm in that situation I'll try below.
Use github copilot in other IDE like VScode. I prefer Rstudio so much but to check it's problem of github copilot or Rstudio.
If this approach works, it may think as Rstudio's problem. but You mentioned as other PC doesn't work at all. So it's not problem with Rstudio but your system.
If you try Rstudio server instead of Rstudio, or used some environment variables with system, or using proxy servers check this issue may help.
However, some people also have similar issue (with copilot auth in Rstudio) #1, #2, #3 which seems to be not solved yet.
This was very helpful. It appears that Copilot is now working. The issue seems to be that further activation was required inside Github, despite Github having said that it was already working.
