Crystal: OpenSSL Error: 1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

[nchapman]

I'm seeing errors when connecting to certain sites over https such as:

• https://www.forbes.com/
• https://www.usatoday.com/

Here's some code the produces the error for me:

require "http/client"

# also happens with https://www.forbes.com/
response = HTTP::Client.get "https://www.usatoday.com/"

This is the error that I get when I run it:

~ crystal ssl_error.cr

I'm running macOS 10.12.5 and have crystal installed via brew:

Any help would be greatly appreciated! Thanks!

Looks like an issue with openssl or the ssl config of the servers itself.

openssl s_client -connect www.usatoday.com:443

Returns

CONNECTED(00000003)
62789:error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version:/BuildRoot/Library/Caches/com.apple.xbs/Sources/OpenSSL098/OpenSSL098-64.50.6/src/ssl/s23_clnt.c:593:

[benoist]

Yep, OSx version is broken. The homebrew version works as expected

brew install openssl

crystal your-file.cr --link-flags '-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib'

Can we close this?

Hi, I'm using Xcode version 7.0
I'm studying iOS programming, I'm trying to create a repository and I received this error:
SSL Error: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version (-1)

does somebody help to me saying what should I do? thanks

Try updating your git installation! This happened on an old computer that was running < 2.0

Hi, I'm having the same problem.
I'm running git version 2.3.5.
If I try this command
openssl s_client -connect www.usatoday.com:443
it works fine.

Hey folks, this is not a general Github nor git support forum, this is the issue tracker for the Crystal programming language hosted on Github.

Let's lock.
