    java.lang.IllegalArgumentException: Illegal character in authority at index 7: http://127.0.0.1:2222${server.contextPath}/actuator/health

        at de.codecentric.boot.admin.server.cloud.discovery.EurekaServiceInstanceConverter.getHealthUrl(EurekaServiceInstanceConverter.java:45)

and I have this properties defined in my yml file

server:

  servlet:
    contextPath:
Solution

  • Just remove 

     servlet:
     contextPath:

    and try hitting your API.

    If you want default path of the application then 

    servlet:
 contextPath: /api

    Then your API looks like : 

    http://127.0.0.1:2222/api/actuator/health
