51192 - SSL Certificate Cannot Be Trusted .

The following certificate was at the top of the certificate

chain sent by the remote host, but it is signed by an unknown

certificate authority :

|-Subject : C=ID/ST=Jakarta/L=Jakarta/O=AXI/OU=abi IT/CN=xxxxx.abi.local

|-Issuer : C=ID/ST=Jakarta/L=Jakarta/O=AXI/OU=abi IT/CN=xxxxx.abi.local

Answer 1

Hello rojak,

Thank you for posting in Q&A forum.

Usually, because the intermediate certificate is not in "Intermediate Certification Authorities", or the root certificate is not in "Trusted Root Certification Authorities".

For example 1:

root-CA certificate should be in "Trusted Root Certification Authorities" and a-subCA-CA should be in "Intermediate Certification Authorities".

For example 2:

root-CA certificate should be in "Trusted Root Certification Authorities"

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Best Regards,

Daisy Zhou
