RQM Copy Utility - Error received: 400 and 404 Failure, Internal Server Error

I was able to run the RQM copy utility with the command below. It ran for over an hour and ended with an error in the logs. It partially copied about 10% (161 TC's and 17 TS's) of the test cases and scripts before it failed.  It did not copy any test plans, execution results or attachments.

 "C:\Program Files (x86)\Java\jre1.8.0_111\bin\java" -jar RQMCopyUtility.jar -s=https://clmtest.rqm.hq.xxx/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/EST_TIO_CLM_QM -us=Admin -pws=Admin -d=https://clmtest.rqm.hq.xxx/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/APP_EST_INT_E2E+CLM_QM_2 -l=importlog.txt

The RQM Copy Utility log file is over 5000 lines long. Below included the last few lines from the log file and the command used. Last few lines from importlog.txt:
