Upgrade BO4.0 to BO4.1. Promotion Manager: Could not reach CMS

Hi Everyone

We recently upgraded our BO Dev and QA environment from BO 4.0 SP4 Patch 5 to BO 4.1 SP3 (no patch).

Promotion Problem:

Source:                 Destination:                Result:

Prod (4.0)              Dev / QA (4.1)             Success
Dev / QA (4.1)        Prod (4.0)                   Success

Dev (4.1)                QA (4.1)                     Error

QA (4.1)                Dev (4.1)                     Error

So we are able to promote between 4.0 and 4.1, but not between 4.1 and 4.1.

We get the following error if we try to promote between 4.1 and 4.1. It happens when you try to connect to a different 4.1 system as the source or destination.

"Could not reach CMS *********** Specify the correct host and port and check for network issues. (FWVM 20030)"

Any ideas?
