I am trying to implement reading blockchain events using web3j (v4.8.7)

/*
 */
@Slf4j
@Component
public class ContractEventSubscriber {

    @Autowired
    Web3j web3j;


    @PostConstruct
    public void init() {
        log.info("Initializing...");
        web3j.blockFlowable(false).subscribe(
                block -> {
                    log.info("New block {}", block);
                }, error -> {
                    log.error("Event error: {}", error, error); //!
                });

        log.info("Initialized.");
    }

}

and this init already fails, with warning The filter has not been found as if something was missing or got lost:

Solution 1:^[1]

This seems to be connectivity issue, once ensured that it can connect to blockchain node, the issue is gone.
