Certificate not signed by trusted authority

We have been been communicating with Twitter from our iSeries. Recently Twitter increased their security and now required a digital certificate. We followed all the setup instructions but get this error on the green screen.

 gsk_secure_soc_init() failed with rc = 6000 and errno = 0. 8 rc of 6000 means Certificate is not signed by a trusted certificate authority.

The certificat we created is linked to the local certificate authority delivered with our iSeries.

What is required to establish the trusted certificate authority?

Any help would be greatly appreciated.

Thanks. We'll let you know when a new response is added.

Finally got an answer. IBM ran a trace that determined we needed a specific Certificate Authority, which they sent. It was a 1K text file, which we imported into the IBM i using Digital Certificate Manager.

Once the certificate authority was installed the software started working right away.

    Recently Twitter increased their security and now required a digital certificate. Can you link us to the Twitter documentation on this, please? Are they requesting a client-side certificate? Tom

    Hi, I have the same 6000 error code, just when the same API tries to make the handshake between my server and the other server. Where can I download the IBM's certificate?

    Hello, we have the same problem, especially with the certificates issued by GoDaddy. Is it possible to have the file you used? Or where can we download it? Which Certificate Authority was it for? Thank you.

    It may be a different issue. I'm seeing a lot of certificate issues as browsers are tightening security. Our networking guys here said the issue will only get worse as things go forward. A lot of sites were taking advantage of using others certificates as an exploit. Everything is being validated now and causing things to fail in some cases. Firefox was causing me a lot of headaches because of this. Site would view fine in IE / Edge / Chrome but fail in Firefox.
