Can you help me solve this problem? Thank you

STEP1: sudo systemctl stop rippled STEP2: ripple_lib get this logs,

STEP3: I use the ripple-lib in my program. Is there any configuration correctly?

const Remote                           = require("ripple-lib").RippleAPI;
const {node: {server, timeout}}  = require("config");
const remote                            = new Remote({server, timeout,});

remote.on("error", (code, msg) => {
    logger.info(`server=${server}||code=${code}||msg=${msg}||OnError()`);
});
remote.on("connected", () => {
    logger.info(`server=${server}||OnConnected()`);
});
remote.on("disconnected", (code) => {
    logger.info(`server=${server}||code=${code}||OnDisconnected()`);
});

class RemoteConn {
    static async init() {
        await remote.connect().catch(utilImp.onExceptionError);
    }

    static async close() {
        return await remote.disconnect().catch(utilImp.onExceptionError);
    }

    static isConnected() {
        return remote.isConnected();
    }

    static async request(parameter, method, ...options) {
        const start   = Date.now();
        const wsreqid = utilImp.get32UUIDString();
        let reqTrace  = {
            reqid:   parameter.reqid,
            wsreqid,
            method,
            options: JSON.stringify(options || null),
            msg:     "WebSocket request begin...",
        };
        logger.info(reqTrace);

        let result;
        try {
            result = await remote[method].apply(remote, options);
        } catch (err) {
            let {code, subCode} = errImp.getWebsocketErrorCode(err);
            if (err) err.reqid = `${parameter.reqid}||wsreqid=${wsreqid}||onWebSocketError()`;
            result = errImp.getExceptionData(code, subCode, err);
        } finally {
            const ms     = Date.now() - start;
            let resTrace = {
                reqid: parameter.reqid,
                wsreqid,
                method,
                body:  JSON.stringify(result),
                cost:  `${ms}ms`,
                msg:   "WebSocket request end.",
            };
            logger.info(resTrace);
        }
        return result;
    }
    }
