Cause
The certificate used for SSL has not been imported into the FME Server cacerts truststore or is a self-signed certificate.
Resolution
Obtain a copy of the CER file and import it into the FME Server cacerts truststore.
- Login to FME Server using a web browser (e.g. Google Chrome)
- View the “Certificate Information”
- Select “Copy to File…”
- Save as a “Base-64 encoded X.509 (CER)” to local disk (e.g. <certpath>\mycert.cer)
- Using the Command Window (as an Administrator), set the directory set <FMEServer>\Utilities\jre\bin
- Enter the following command, making the appropriate changes to <FMEServer> and <certpath>:
keytool -import -trustcacerts -keystore <FMEServer>\Utilities\jre\lib\security\cacerts -storepass changeit -noprompt -alias mycert -file <certpath>\mycert.cer
You may also see errors similar this when configuring Active Directory with SSL encryption.

keytool -import ... is now keytool -importcerts this will affect newer versions of Java.
