After the service restarts, requests do not come through.

The question

There are two services, server-a and server-b, each with two instances. server-a will call the server-b service, and after one instance of server-b restarts, all traffic will go to the other instance of server-b.

The application's environment

• Spring (boot):3.0.2
• grpc-java:1.51.0
• grpc-spring-boot-starter:2.14.0.RELEASE
• java: version + architecture (64bit?)
  java 17.0.5 2022-10-18 LTS
  Java(TM) SE Runtime Environment (build 17.0.5+9-LTS-191)
  Java HotSpot(TM) 64-Bit Server VM (build 17.0.5+9-LTS-191, mixed mode, sharing)

Additional information

Shutting down the service will print the following information, restarting will not print it

Adding the following configuration will work，I think it was because the service list was not refreshed when the GRPC service was restarted.

spring:
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true
