Spring Cloud Netflix Apps don't re-register after server restarts

This may be a duplicate of #26, but that seemed to be some kind of authentication issue and I don't believe this is. Client apps start fine and connect to the server, but upon killing and restarting the server, none of them re-connect.

Client logs:

2023-01-06T03:53:46.208Z  WARN 37592 --- [tbeatExecutor-0] c.n.d.s.t.d.RetryableEurekaHttpClient    : Request execution failed with message: Error while extracting response for type [class com.netflix.appinfo.InstanceInfo] and content type [application/json]

There doesn't appear to be any log acknowledging this attempt on the server. I have both client and server configured with the default options - no additions in any application.yml.

@bchilcott
Have you checked related solution at #4145 for server side ? that fixed issue for me. Error handling for client side restTemplate is missing as i saw. when empiting the content to bypass cleint side error eureka able to renew the lease.

any solution for this? @GilbertHG

You can add one end poitm to your Eureak server tp bypass the error content then it iwll work but keep follow the permanent solution

@RestController
static class CustomErrorController implements ErrorController {

    private static final String ERROR_MAPPING = "/error";

    @RequestMapping(ERROR_MAPPING)
    public ResponseEntity<Void> error() {
        return ResponseEntity.notFound().build();
    }

}
