Trunk cannot be activated due to the following: Invalid Internal IP address. Please choose a different IP.

Hi:

We have applications published in the HTTPS trunk. We have confirmed that the applications published via HTTPS trunk are all working.     When we setup HTTP -> HTTPS redirection for the trunk,  we get an error on activation that says.

Error: Trunk 'xxxxx' cannot be activated due to the following: Invalid Internal IP address.  Please choose a different IP.

Once I delete the http -> https redirection I'm able to successfully activate.

 Our configuration for this setup.

* 1 HTTPS  trunk configured with 2 servers in an array configuration.  

* We are not using integrated NLB.

I'm kinda stumped on where to start troubleshooting.   Could you help figure this out?

Thanks in advance for your help.
