Hi Guys
Thanks on all of your replies.
Andrew the SelfSigned Cert is imported on the ICM_SSL_XXXX and TrustedCAs keystore and also on the Users - Certificate tab. Even that the problem persist. Have you done this type of configuration successfully before?
I am going to test Steven's idea. It sounds like a way to pass the cert chain... I don't know if this could be a viable approach in a productive scenario.
I'll let you know it turns out.
Regards
Henry
