Even after successful installation or upgrade of Access Gateway, the health shows failure in starting ESP. After an fresh import of Access Manager Appliance in the Administration Console, the Access Gateway Health displays “ESP Failed to initialize : Unable to read <keystorefilelocation>”. The keystore file can be Connector, Signing, Encryption or Truststore.
To workaround this issue:
On the Access Gateway, go to the <keystorefilelocation> location as specified in the health error message.
Delete the files indicated in the ESP error message.
In the Administration Console, click Auditing > TroubleShooting > Certificates.
Enable the device that has been deleted in the Access Manager Appliance and it needs to be re-pushed.
Click Re-Push Certificate.
Restart server provider of the Access Gateway.
