@khandah I see non SSL setup is working fine for you. The post is specific to non-SSL setup. Create a new thread in the forum with specifics you have tried and someone would be able to provide directions.
From ACS 7.x on-wards legacy transformation service is no longer available. We have to use the local transformation service if we have requirements for transformations/previews etc. Many folks in alfresco community are confused on setting up legacy Vs local transformation service. The purpose of this post is to document all the steps at one place when setting up ACS-7.0.0 manually using distribution package if docker / ansible is still not an option for you.
