Hi,
Please review your configuations:
1. Environment variable SECUDIR
You need set it to E:\usr\sap\<SID>\DVEBMSGXX\sec.
For the user which is used to start saprouter, you need to set user variable. don't mix up user for saprouter and R3 system.
2. SNC name
snc/identity/as p:SAPService<SID>@DOMAIN
You have set to use sapcrypto library. In this case, you need to use format like:
p:CN=sap01.hostxx, O=myorganisation, C=DE
I recommend you check your settings as described in the following link:
SAP Library - SAP NetWeaver by Key Capability
Thanks.
Jim
