We are Installing CMS and Topology using PowerShell scripts.
In our installation scenario we have two servers in a load balanced configuration.When we run the CMS installer both in the GUI and as a script we get the same behaviour.Installing both CMS and Topology on port 80 with Host headers for the load balanced endpoints cms.dev.domain.com and topology.dev.domain.com
The specified configuration conflicts with another application or Web site configured on this machine. Select a different IP address, port number or host header.
I tried with 3-4 different ports nothing worked.
Before that error occurs below message displayed
Setting string variable 'WEB_INFOS_SHARED' to value '3:SDL Web Topology Manager:(All Unassigned):topology.dev.domain.com:82'
Try to resolve the above issue using the below SDL Community Article Nothing worked.
Appreciate your help
