1. Situation
Pressing the 'Apply to Environment' button in Deploy Architecture led to an 'Update rollback complete' state.
2. Problem
The problem in this case was that two routes were pointing at the same port configured in Deploy Architecture.
3. Analysis
3.1 Reproduction
N/A
3.2 Analysis
We started off by checking the CloudFormation in AWS. Here, it was indicated that different routes were pointing to the same port. Therefore, the architecture of Deploy was checked to verify whether this was the case. Here, it was found that indeed there were two routes pointing at the same port.
4. Result
Once one of the routes was removed (in this case this route was obsolete) updates could be done without any problems.
