R help - Oct 2022 - R version 4.2.1 install.packages does not work with IE proxy setting

Petr, 
You also might want to check out the bug reported here:

https://bugs.r-project.org/show_bug.cgi?id=18379

it was fixed and the last two comments discuss how to handle it in Windows:

you add a new User Environment Variable:
R_LIBCURL_SSL_REVOKE_BEST_EFFORT and set it to TRUE

This fix is in R-4.2.1 Patched (I don't know if it has made it out to the
full distribution) and works in my 'corporate' environment.  Perhaps it
also applies to your environment.

Tim

Thanks,

the workaround works but we need try the "permanent" solution with
Renviron.site file in future.

Cheers

Hallo Howard

Thanks, for the time being the previous workaround with wininet options
works for me. I will wait for the new R version and then try to persuade our
IT to make relevant changes.
