mmh.. for some reason the original post in this thread is only showing
up now in my mailbox i.e. way after Steffen's answer (and even if
Steffen's answer includes the original post, I must confess that I
didn't really pay attention to it)
Anyway, based on that original post I see now that Egon was using
download.file() but this was not working on Windows 10 so he switched to
the RCurl solution. And the RCurl solution works on Windows 10 but now
fails on our Windows builders (Windows Server 2012 R2 Standard). Do I
get the situation right?

site <- basicTextGatherer()
curlPerform(url=url, writefunction=site$update, .opts=opts)
html <- site$value()
Not sure why this fails on our Windows builder but if it fails there it
might fail on other Windows systems. A more portable/reliable way to get
that HTML document is to use download.file():
url <-
"https://urldefense.proofpoint.com/v2/url?u=https-3A__bridgedb.github.io_data_gene-5Fdatabase_&d=DwIDaQ&c=eRAMFD45gAfqt84VtBcfhQ&r=BK7q3XeAvimeWdGbWY_wJYbW0WYiZvSXAJJKaaPhzWA&m=GbdGtFXiT4WW33h7Un9R0XL7r4I1e4JAb9uSyup82Sw&s=qywf3a1JViBPl5ArNq4vLqt8_csFrFDG_G2MREAWwpM&e=
"
destfile <- tempfile()
download.file(url, destfile)
html2 <- paste0(readLines(destfile), "\n", collapse="")
identical(html, html2) # TRUE
This works everywhere I tested e.g. my laptop, malbec1, merida1, tokay2,
etc... and doesn't rely on some obscure RCurl/SSL settings.
By doing the same kind of change in their getDatabase() function, the
BridgeDbR maintainers can get rid of their dependency on RCurl.
Hope this helps,
H.

Hi,
can you get me the URL that wants to be downloaded ?
The "tlsv1 alert protocol version" indicates that the proper
solution might be to notify the server to reconfigure
the web server supported TLS versions.

Hi all,
in the BridgeDbR package I have a TSL issue, just on Windows10 [0]:
location <- getDatabase("Bacillus subtilis")
Error in function (type, msg, asError = TRUE) :
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert

Calls: getDatabase ... getBridgeNames -> curlPerform -> <Anonymous>

Execution halted
This method is using the download.file() method (see [1]). I am not
sure
what this method uses by default. I have been googling and found a
number
of suggestions on how to get RCurl to use other SSL version, such as:
CURL_SSLVERSION_TLSv1_2 <- 1Lopts <- RCurl::curlOptions( verbose =
TRUE, sslversion = CURL_SSLVERSION_TLSv1_2)download.file(url, file,
mode = "wb", .opts=opts)
But I haven't found something that works. Error messages are very
cryptic,
and I'm running out of ideas.
Does someone have a suggestion how to debug this? Maybe even have a
solution?
All feedback is very much appreciated!
Egon
