Backend ECC connection to CPI

[former_member1002059]

I am getting error 'SSSLERR_SERVER_CERT_MISMATCH (-30)#Server certificate does not match supplied TargetHostname##SapSSLSessionStartNB()==SSSLERR_SERVER_CERT_MISMATCH# TargetHostname' while testing trial-CPI service from ECC. I have created http connection in SM59 and added the required certificate in STRUST. Earlier there was another issue that I was getting Certificate Missmatch error and I checked the ICM log and found that server was expecting certificate with CN as 'CN=*.cf.eu10.hana.ondemand.com, O=SAP SE, L=Walldorf, C=DE'. Then I got this certificate from 'login.cf.eu10.hana.ondemand.com' added it to STRUST and now I am getting 'Hostname' mismatch error however I can see the entry *.cfapps.eu10.hana.ondemand.com' with DNSName it the certificate.

Thanks,

Deepak

Hello Deepak,

Confirm that the parameters "icm/HTTPS/client_sni_enabled" and "ssl/client_sni_enabled" are set to "TRUE".

In fact, only the latter would be required if you are using a recent SAP kernel release/patch level.

Thanks for your response Isaias,

I have added the parameters you mentioned, However I am getting warning for 'icm/HTTPS/client_sni_enabled' -

Also now the error has changed to information pop-up -

I am getting below error when testing the outbound proxy -

Hello Deepak,

You are welcome!

It seems that the screenshots did not come through, so I cannot see what you tried to show...

Hi Deepak,

Can you please try by adding both root and server certificate of CPI in STRUST.

Also, You should be adding CA certified ECC certificate in CPI keystore.

Thanks Vijay for your response, I have tried with both CPI's root and root +Server certificates in STRUST.

Also I have already uploaded the ECC certificate to CPI keystore.

Do you have any other recommendation?

Hi Vijay,

I have downloaded the certificate from Connection test -

Also I don't have above mentioned certificate in the Keystore -

Thanks,

Hi Deepak,

You may please address me as Vinay 🙂

Since your tenant is trail account. The certificate may not be available.

Can you please import the server certificate obtained from connection test in CPI key store and try testing again.
