Hi @ReeseFacendini . I work with @JohnSteed1 . We don't have an ALB per se, but we have a lot of other machinery which include Certs and SSL, fronting our ArcGIS environment. By the time we reach our ArcGIS environment, we can safely using HTTP from a security perspective. But we don't know whether this will come back to bite us in other ways, and are seeking guidance on that.
My limited knowledge of this subject suggests that the use of HTTP instead of HTTPS is lightly documented. For example, I believe that we can subtract (443-80) from many port numbers to reference an HTTP port, e.g. 2080 on arcserver instead of 2443.
