Link abapGit repository issue: "SSL handshake with github.com:443 failed"

KarynaB — Tue, 12 Mar 2024 09:56:19 GMT

Hi,

I am getting the error when I am trying to link the git repository in the SAP BTP ABAP Environment:

"HTTP error 421 occured: SSL handshake with github.com:443 failed: SSSLERR_PEER_CERT_UNTRUSTED (-102)
Peer's X.509 certificate (chain) validation failed (missing "

Any idea what could be the reason?

Thanks.

Tested, same situation here. I guess we need some support 😀

The problem is known. For a workaround (upload of the certificate) see my following post:

in the trial systems I have uploaded the new certificate so that it should work there again.

HTTP error: [421] SSL handshake with api.github.com:443 failed: SSLERR_PEER_CERT_UNTRUSTED (-102) Peer’s X.509 certificate (chain) validation failed (missing...)

This occurs when your ABAP system (SAP NetWeaver) is trying to connect to GitHub over HTTPS, but cannot trust the SSL certificate chain. What to do now ?

You would have to install the certificate in SAP NetWeaver ABAP AS using transaction STRUST.
