Cause

Following is an example which shows the incorrect configuration for both admin and reporting HTTPS ports:Flexnet Site configuration on Admin server:
Flexnet Site configuration on Reporting server:
Workaround
Following is a workaround to fix this issue:1. Stop both admin and reporting servers using the command 'flexnet stop' on the command line from the respective admin or reporting installed directories, .../flexnet/manager/admin or .../flexnet/manager/reporting.
2. Run flexnet site from admin server and make changes to HTTPS port for the Reporting server HTTPS port and similarly run flexnet site from reporting server and make changes to HTTPS port for the admin server. Below is an example which corrects the HTTPS ports for both servers that were incorrectly shown in the above example:
Please note that the HTTPS port numbers shown above are for demonstration purpose only. Please use your own port numbers as set in your system environments.
3. Start reporting server first by typing 'flexnet start' at command line or turn on the service 'FlexNet Manager for Engineering Applications Reporting' from the Services page.
3. Next start the admin first by typing 'flexnet start' at command line or turn on the service 'FlexNet Manager for Engineering Applications Admin' from the Services page.
