Can you try to connect with openssl(1) command, and provide messages ?

openssl s_client -connect github.com:443 -msg

In my Fedora23 with LibreSSL 2.2.7, it succeeded like this.

You could successfully connect with openssl(1) s_client since it showed Verify return code: 0 (ok) .
But your curl command failed while SSL/TLS handshake phase soon after sending "Client hello".
Are your openssl command and curl command linked to the same LibreSSL 2.2.7 library ?

chengtengfei · 2018-01-16T01:51:16Z

I met the same issue, need help!!!

akeschmidi · 2018-01-19T10:41:12Z

Same here 😩

kinichiro · 2018-01-19T13:17:04Z

We would like to more information to investigate this issue. - Can you connect other host via SSL with curl ? - Or you can't connect any host via SSL with curl ? - Are there any hosts you can connect ?

benoittgt · 2018-01-22T06:26:52Z

I'm having the same issue with rust install.

Current installation options:

   default host triple: x86_64-apple-darwin
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation
1

info: syncing channel updates for 'stable-x86_64-apple-darwin'
error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256' to '/Users/bti/.rustup/tmp/p6goif8zcrom0hl5_file'
info: caused by: error during download
info: caused by: [35] SSL connect error (LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to static.rust-lang.org:443 )

Curl version

curl --version
curl 7.57.0 (x86_64-apple-darwin17.2.0) libcurl/7.57.0 SecureTransport zlib/1.2.11

Osx 10.13.2

benoittgt · 2018-01-22T09:51:59Z

I update with brew, libressl, openssl and curl and reboot my machine. It's now working.

4a6f656c · 2018-01-28T13:41:55Z

@jiahut 2.2.7 is pretty old (May 3, 2016) - I'd strongly recommend upgrading to a current version and testing again.

@benoittgt Did that result in a newer version of libressl?

jiahut · 2018-01-29T02:44:49Z

@4a6f656c the macOs10.13.3 system with LibreSSL2.2.7 as default

benoittgt · 2018-01-29T09:01:58Z

@4a6f656c I don't have anymore the error

busterb · 2018-01-31T21:21:34Z

That's probably more of an Apple question, since whether macOS ships with a 1.5 year old version is a little out of our hands

I'd also presume that Apple has local modifications and would largely be responsible for supporting the version that ships with the OS. I'm going to close this because we don't have much we can do on this end as upstream.

ghost · 2018-02-08T17:33:47Z

I know this issue is closed, but just in case anyone happens upon it.

I can confirm this is still broken in macOS 10.13.3 with the following details from curl:
curl --version curl 7.54.0 (x86_64-apple-darwin17.0) libcurl/7.54.0 LibreSSL/2.0.20 zlib/1.2.11 nghttp2/1.24.0 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz HTTP2 UnixSockets HTTPS-proxy
Workaround: install curl, libressl from brew and use the binary located at /usr/local/opt/curl/bin

yujunz · 2018-02-11T07:11:50Z

I got the same error even after upgrading curl, libressl and openssl. It turns out to be an issue of the corporate HTTP proxy issue.

Leave a note here in case somebody met the same problem.

akeschmidi · 2018-02-22T05:11:59Z

a note ;-)

wizofe · 2018-02-24T08:27:59Z

Thanks @benoittgt, your solution worked liked a charm. It seems I was missing libressl (ups!)

Papamilo · 2018-02-26T09:50:56Z

Hi guy got the same isue with Mac OS High Sierra 10.13.3 :
LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443 when I try to clone a github repo or any npm command
Even when I try install brew like so /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" I got this too curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443
I also tried the alternative setup https://docs.brew.sh/Installation ...same..if anyone got an idea

AsceticBoy · 2018-04-19T04:54:18Z

@benoittgt What is you solution ? Can you tell me step-to-step, I have some question with install Rust

electriquo · 2018-04-20T13:25:24Z

i have installed libressl, openssl and curl using brew. regardless which curl i used, original curl and brewed curl, i get the SSL_ERROR_SYSCALL error

i have no problem downloading the file using wget.
when i pass --no-alpn to curl it bypasses the issue.
does any one have a fix for it, while not passing --no-alpn to curl?

bob-beck · 2018-04-20T23:43:38Z

neither of those appear to be using anything close to a supported version of libressl. your second one appears to be using openssl.
