SUM -HTTPS connection issue with SSLERR_PEER_CERT_UNTRUSTED

Verification of HTTPS connection during upgrade.

While upgrading JAVA Portal with https protocol enabled.

When 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.

if 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.  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.

So need to fix applying certificate as posted in another page in this blog. then you can do upgrade.
