The following command returns an error: "Error: sits_cube: BDC is not accessible"

# Provide your BDC credentials as environment variables
Sys.setenv(
    "BDC_ACCESS_KEY" = "<TOKEN>"
)

# create a raster cube file based on the information in the BDC

It seems that the error is related with curl version installed in SO.

# try with curl
RCurl::httpGET("https://brazildatacube.dpi.inpe.br/stac/")

# try using native R url() function
readLines(url("https://brazildatacube.dpi.inpe.br/stac/"))

The first command generates the error error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

The second works finely.

sits uses RCurl package to test if an url is working. I think that the error can be avoided by using httr package instead RCurl.
