Unable to load io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider

See original GitHub issue

Expected behavior

Spring Cloud Gateway microservice (api-gateway) should route to appropriate microservice (web) using Eureka Discovery Server microservice (discovery) and return “Hello World”.

Actual behavior

      <version>4.1.73.Final</version>
