abapGit SSSLERR_PEER_CERT_UNTRUSTED

Hi Experts,

sorry most probably for a stupid question, but it seems that github has recently change the SSL certificates and since than I could not add ABAP Git Repository in the ADT due to this error:

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

Any experience with this issue? Is ADT using my user or computer certificates stores to check the trusted CAs? Or is it some config in Eclipse?

Many thanks for any hints.

Milan

Hi Raymond, many thanks for your answer, but I'm talking about ADT(Abap development Toolkit) running on my notebook and trying to connect to gitHub from there... Not sure this has something to do with AS ABAP.

Did you search? If it's about BTP, I can find this: https://ga.support.sap.com/dtp/viewer/index.html#/tree/2065/actions/32308

Hi Sandra,

that is also an issue between AS ABAP and BTP, Cloud Integration... Basically the same issue, just the client in my case if my notebook, where Eclipse with ADT is running and the server is github.com.

The solution is the same, importing the certificate of Certificate Authority somewhere ;-), question is where...

BR,

Where? But it's ALL explained in the SAP note. You have around 9 points to check.

Hi Sandra, what confused me was the STRUST transaction, because I'm working on a project for S/4Hana Cloud System... There of course is no STRUST transaction, but a fiori App: Maintain Certificate Trust List, where this new certificate needs to be imported...
