Run the following in Script Console and report the output:
println Jenkins.instance.rootUrlFromRequest
println JenkinsLocationConfiguration.get().url
println
org.kohsuke.stapler.Stapler.currentRequest.getHeader('X-Forwarded-Host')
println
org.kohsuke.stapler.Stapler.currentRequest.getHeader('X-Forwarded-Port')
