In the process of submitting a package to CRAN I'm trying to run check_win_devel() and check_win_release() from devtools; both throw the error outlined above. Tried both with rstudio on windows and rstudio-server on wsl. After extensive Googling I haven't been able to find a workaround; I'm pretty clueless at this stage. Anyone came across the issue yet?

Thanks.

Those two devtools functions submit your package to an external machine at win-builder.r-project.org for testing. It looks as though that machine isn't allowing connections to receive your submission (maybe it's offline for the holiday break) or during tests your submission is trying to connect somewhere else, and that's failing.

I'd recommend following the instructions on win-builder.r-project.org for submitting your package instead of relying on devtools functions to do it. Then you'll see the errors first hand if it's a submission problem.
