Hello ,

We have a service running in WebService Proxy and while communicating this service the other parties are received Forbidden 403 error.

While in DP logs it shows the below

source-https (GSB_IGOV_HTTPS_FSH): Request processing failed: Connection terminated before request headers read because of the connection error occurs, from URL: 10.1.161.5:56907
valcred (GSB_IGOV_ValidCred): SSL Proxy Profile 'GSB_IGOV_SSLProfile': connection error: peer did not send a certificate


Certificates are placed the Valcred of SSL Profile but still it shows SSL exceptions in DP and Forbidden error 403 in applicatiion.

Any where we need to place the certificate other valcred?

Communication is there and the certificates are exchanged from DP as well as the receiving application.

But still am receiving this error.

I added this certificate in SSL Proxy profile. Is that the only place we will add certificates or there are other places which needs to be added?

Hi, You are not ever getting to that stage of val cred ,

Peer has to accept your connection and send a certificate which is not happening.

Do a packet capture you will get the whole picture.

There could be 2 issues, Peer is not trusting your connection or failing at the firewall level.

Hello ,

Just did a packet capture and the requests are successfully acknowledged and finished. So the requests did hit the server after passing through firewall.

Any other places to check for this?

Are you sure that the certificates were passed?

Are you sure that the certificates are valid?

Are you sure that DP is configured to accept the certificates?

What I meant is - are you sure that DataPower is configured to accept *these particular* certificates.

Including the full signer chain?

Hello MQJEFF ,

I am not sure how we can make sure the DP can accept these particular Certificates.

Is there any permission or access we need to grant to Valcred?

I'm not really a DP user/expert. But I would think you would need to upload the relevant keys/signer certificates.

Presumably in the same way you did for the others that are working.
