Error installed R library with version 3.6.0 when only version 3.4 is required

Question

I´m trying to install the library ssev: https://cran.r-project.org/web/packages/ssev/index.html

On a machine with R 3.6.0

install.packages("ssev")

And I´m getting the following error:

“unable to access index for repository http://cran.rstudio.com/src/contrib:
  cannot open URL 'http://cran.rstudio.com/src/contrib/PACKAGES'”
Warning message:
“package ‘ssev’ is not available (for R version 3.6.0)”

What I do not understand is why I´m getting this error, when the requiered version for this library is 3.4, as shown in CRAN:

The installation does work with a more recent versions of R like 3.6.3, but in the machine I need it I do not have the option to install a newer version.

I'm using R version 3.6.1 and only getting a warning about the using the library. Generally, you can ignore these and it will still work. If it's not, try updating the package and post the results of trying to load the library and also run version to show info on your setup as I did below:

 > library(ssev)
Warning messages:
1: In recycle.data(data, FALSE, length(x), units) :

2: package ‘ssev’ was built under R version 3.6.3
