Spring Cloud Netflix eureka.instance.hostname not respected in UI

spring-cloud-starter-netflix-eureka-client 2.2.2.RELEASE

for my client service, I have the following config:

spring.application.name=XXX-Config

eureka.instance.hostname=config01.xxx.com eureka.instance.non-secure-port-enabled=false eureka.instance.secure-port-enabled=true

A separate client referencing XXX-Config DOES get the correct URL: https://config01.xxx.com, however, the Eureka UI still shows XXX-Config mylocalpc.mshome.net:XXX-Config:9345

/eureka/apps has:

<instance>
<instanceId>mylocalpc.mshome.net:XXX-Config:9345</instanceId>
<hostName>config01.xxx.com</hostName>
<app>XXX-CONFIG</app>
<ipAddr>...</ipAddr>
<status>UP</status>
<overriddenstatus>UNKNOWN</overriddenstatus>
<port enabled="false">9345</port>
<securePort enabled="true">9345</securePort>
<countryId>1</countryId>
