Certificate Exception Error - SAP PO connecting to our Web API - we have a Let's Encrypt Certificate


#1

Hello,

Error

  • SSLCertificateException

Background

  • Our client is trying to connect to a SOAP API on our web server
  • They are using SAP PO (Process Orchestration)
  • We have a Let’s Encrypt Certificate installed

Query

According to my reading of the following:

Should they be installing this Root CA in their Certificate Store ?

  • Issuer “DST Root CA X3.”

Hi,

This isn’t related to LE, since the certificate is valid.

Please check this post for more information.

Hello stevenzhu

Thanks for the quick and helpful response.

I have just received a detailed email message from the client.

child : CN=qa.XXX.XXXXXservices.com
intermediate: CN=Let’s Encrypt Authority X3,O=Let’s Encrypt,C=US
root : CN=DST Root CA X3,O=Digital Signature Trust Co.

So they do have the correct root CA.

This new information from them:
“From the HTTP logs, we see that the chain verifier is referring to 2 certificates”

… which refers to our hosting server, so I am following up there with our Hosting Service Provider.

Thanks again.

The Let’sEncrypt part appears to be all good.
