500 error: could not start rstudio in time

I am facing an error while running the binder for R. I have tried with two different R files but getting the same result.

500 : Internal Server Error
The error was: could not start rstudio in time.

Do you mean GitHub - binder-examples/r: Using R with Jupyter / RStudio on Binder ? Or GitHub - binder-examples/r-conda: R and RStudio via conda packages in repo2docker ?

For GitHub - binder-examples/r: Using R with Jupyter / RStudio on Binder :
I just launched Jupyter first then opened RStudio from the Jupyter dashboard successfully from it. And then, separately launched RStudio directly from it as well.

For GitHub - binder-examples/r-conda: R and RStudio via conda packages in repo2docker : I just launched directly to RStudio with no issues.

Thank you for your reply. It worked at last! I was trying “holepunch” library but it was showing the 500 error but then I followed the steps in GitHub - binder-examples/r: Using R with Jupyter / RStudio on Binder and it worked.

So it sounds like Holepunch is your issue, not Binder. You would go to Holepunch to seek help in that case. Maybe your issue with Holepunch may be the most recent issue filed there?
