SAP SUM https connection error SSLERR_PEER_CERT_UNTRUSTED

Verification of HTTPS connection during upgrade.

Recently we are upgrading our JAVA Portal which is running on DMZ with https protocol enabled.

While starting SUM SP16, it’s started by default http but if SUM detect system is running on https, it’s get converted to https automatically.

We are facing issue while it’s asking for adm credentials. it’s not accepting the credentials & in log file it’s throwing SSLERR_PEER_CERT_UNTRUSTED error. we have checked multiple log files & found that it’s trying to access the system via https protocol.

How to check https connections are working or not before running SUM

SAPCONTROL give you the facility to check the same.

sapcontrol -nr -host -prot NI_HTTPS -function AccessCheck Stop

sapcontrol -nr -host -prot NI_HTTPS -function ParameterValue
SAPPROFILE

Give instance no. & hostname in above fields & run the commands.

The above both commands should return “Access Check” “OK”. if it’s failing with SSLERR_PEER_CERT_UNTRUSTED issue, then SUM will never work. in my case i have tested the above command on my second application server & it works there, i ran the SUM from there & upgrade my portal successfully without any single error.
