Spring Boot App - Consul Discovery - Secure=true not working

Hello,

We have migrated a spring boot app from

springBootVersion = '2.3.2.RELEASE' -> '2.5.2'
springCloudVersion = 'Hoxton.SR6' -> '2020.0.3' (spring-cloud-consul = 3.0.3)

Our consul discovery properties have not changed but the secure=true field is not showing up in Consul anymore. Our service is working over HTTPs but the discovery is not properly registering the service as HTTPs with secure=true. The only things that have changed are the apps spring boot and cloud version, reverting back makes it work again.

I also tried Spring boot version 2.4.6 and a variety of 2020.0.x versions, all producing same issue.

Consul server is version 1.3.0

build.gradle Spring dependencies

			'org.springframework.boot:spring-boot-starter-webflux',
			'org.springframework.boot:spring-boot-starter-tomcat',
			'org.springframework.boot:spring-boot-starter-data-jpa',
			"org.springframework.boot:spring-boot-starter-oauth2-client",
			'org.springframework.boot:spring-boot-starter-mail',
			'org.springframework.boot:spring-boot-starter-actuator',
			'org.springframework.boot:spring-boot-starter-security',
			'org.springframework.cloud:spring-cloud-starter-sleuth',
			'org.springframework.cloud:spring-cloud-starter-bootstrap',
			'org.springframework.cloud:spring-cloud-starter-consul-all',

bootstrap.yml (we are using old bootstrap support)

spring:
  cloud:
    consul:
      discovery:
        scheme: https
        health-check-path: /actuator/health
        health-check-tls-skip-verify: true
        health-check-interval: 30s
        fail-fast: true
        queryPassing: true

Start by reproducing the registration using the listed build.gradle dependencies and bootstrap.yml settings, comparing Spring Boot 2.3.2/Hoxton.SR6 with the newer versions. Check the Consul service registration and confirm that the HTTPS scheme results in secure=true being reported again.
