Hi list,
I'm struggling with git connecting to Github.
The problem might be SSL/TLS related.
https://githubengineering.com/crypto-removal-notice/
I suspect that my setup still uses tlsv1 or tlsv1.1.
I've tried to explicitly set git to use tlsv1.2 in my .gitconfig file
like this:
[http]
sslVersion = tlsv1.2
I've tried to re-compile git with OpenSSL and GnuTLS. All give the
same error.
git clone https://github.com/OnionIoT/source.git

I can connect to other git servers without any error. This is a debian
stable system with the following components:
git version 2.11.0
libcurl 7.52.1
OpenSSL 1.0.2l
Is there any way to know what is the exact protocol used? Are there any
workaround, fix for this issue?
Any help welcome. Thank you,
Levente
