Check that you use the same password for your PFX file you import certificate from as you use for the key.jks file you created for the Controller Web setup.

Update the file config.js in folder D:\Program Files\ibm\cognos\ccr_64\frontend to correct password


“secure”: false //set this to false when you use custom certificates for Controller Web

“ssl”: {
// certificates
“key”: fs.readFileSync(__dirname+”/keyfile.key”), //__dirname points to ccr_64\frontend
“cert”: fs.readFileSync(__dirname+”/cert.crt”),

Update the file server.xml in folder D:\Program Files\ibm\cognos\ccr_64\fcmweb\wlp\usr\servers\fcm.web to correct password


<keyStore id=”defaultKeyStore” password=”TheNewPasswordHere” sslProtocol=”SSL_TLS” />

Save the changes and restart all 3 IBM Cognos Controller Web services.

Wait at least 20 minutes for it to load fully, before you test.
