調査の方向性

まず、添付された2つの consul-client サンプルを実行し、Spring Boot 3.5.11/Spring Cloud 2025.0.1 と Spring Boot 4.0.3/Spring Cloud 2025.1.1 の動作を比較します。Consul エージェントの再起動前後で ConsulCatalogWatch と TtlScheduler を追跡します。Consul の再起動後に、アプリケーションを再起動せずに新しい方のサンプルがサービスを再登録できれば完了です。

説明

waiting-for-triage

Describe the bug
I have a spring boot application (3.5.11) using spring-cloud-starter-consul-discovery (2025.0.1).
I have activated reregister-service-on-failure as the consul may sometimes be restarted.
That works perfectly fine.

Now I'm migrating the app to the lastest version (spring boot 4.03 ans spring cloud 2025.1.1).
Unfortunatly when I restart the consul agent, the app do not re-register anymore.

Sample
1- Here's an example with spring boot 3.5.11 and spring cloud 2025.0.1 (everything works as expected)
consul-client-3.5.9.zip

When I start the app, the service registered :

2026-03-03T15:23:40.271-10:00  INFO 15316 --- [DEMO-SERVICE] [           main] o.s.c.c.s.ConsulServiceRegistry          : Registering service with consul: NewService{id='DEMO-SERVICE-9091', name='DEMO-SERVICE', tags=[], address='10.0.10.5', meta={secure=false}, port=9091, enableTagOverride=null, check=Check{script='null', dockerContainerID='null', shell='null', interval='null', ttl='30s', http='null', method='null', header=null, tcp='null', timeout='null', deregisterCriticalServiceAfter='null', tlsSkipVerify=null, status='null', grpc='null', grpcUseTLS=null}, checks=null}

When I stop the consul agent:

2026-03-03T15:24:39.807-10:00  INFO 9560 --- [DEMO-SERVICE] [TaskScheduler-1] o.apache.http.impl.execchain.RetryExec   : I/O exception (org.apache.http.NoHttpResponseException) caught when processing request to {}->http://localhost:8500: The target server failed to respond

...
Caused by: java.net.ConnectException: Connection refused: getsockopt

When I restart the consult agent, the TtlScheduler is called and the service is re-registered :

2026-03-03T15:24:47.355-10:00  WARN 9560 --- [DEMO-SERVICE] [pool-2-thread-1] o.s.cloud.consul.discovery.TtlScheduler  : OperationException(statusCode=404, statusMessage='Not Found', statusContent='Unknown check ID "service:DEMO-SERVICE-9091". Ensure that the check ID is passed, not the check name.')
2026-03-03T15:24:47.355-10:00  INFO 9560 --- [DEMO-SERVICE] [pool-2-thread-1] o.s.cloud.consul.discovery.TtlScheduler  : Re-register NewService{id='DEMO-SERVICE-9091', name='DEMO-SERVICE', tags=[], address='10.0.10.5', meta={secure=false}, port=9091, enableTagOverride=null, check=Check{script='null', dockerContainerID='null', shell='null', interval='null', ttl='30s', http='null', method='null', header=null, tcp='null', timeout='null', deregisterCriticalServiceAfter='null', tlsSkipVerify=null, status='null', grpc='null', grpcUseTLS=null}, checks=null}

2- Here's the same example with spring boot 4.0.3 and spring cloud 2025.1.1 (re-registering doesn't occured)
consul-client-4.0.3.zip

At startup the service is registered :

2026-03-03T15:32:08.116-10:00  INFO 17028 --- [DEMO-SERVICE] [           main] o.s.c.c.s.ConsulServiceRegistry          : Registering service with consul: [NewService@1d9af731 id = 'DEMO-SERVICE-9091', name = 'DEMO-SERVICE', tags = list[[empty]], address = '10.0.10.5', meta = map['secure' -> 'false'], port = 9091, enableTagOverride = [null], check = [NewService.Check@39afe59f args = [null], dockerContainerID = [null], shell = [null], interval = [null], ttl = '30s', http = [null], method = [null], header = [null], tcp = [null], timeout = [null], deregisterCriticalServiceAfter = [null], tlsSkipVerify = [null], status = [null], grpc = [null], grpcUseTLS = [null]], checks = [null]]

When I stop the consul agent:

2026-03-03T15:33:55.550-10:00 ERROR 17028 --- [DEMO-SERVICE] [TaskScheduler-1] o.s.c.c.discovery.ConsulCatalogWatch     : Error watching Consul CatalogServices

org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8500/v1/catalog/services": null

When I restart the consult agent, nothing happens (no log, no re-register). I have to restart the application.
