mongodb에 내용이 뜨지 않네요 ㅠㅠ

화성땅 수업중인데, 화성땅 전에 user 만들었을 때도 분명 만들었고, db가 떴었는데 어느날 갑자기 안떴는데...이번에도 영문을 모르겠네요 ㅠㅠ

이건 app.py 코드

from flask import Flask, render_template, request, jsonify
app = Flask(__name__)


from pymongo import MongoClient
client = MongoClient('mongodb+srv://sparta:test@cluster0.xmvg6np.mongodb.net/?retryWrites=true&w=majority')
db = client.dbsparta


@app.route('/')
def home():
    return render_template('index.html')


@app.route("/mars", methods=["POST"])
def mars_post():
    name_receive = request.form['name_give']
    address_receive = request.form['address_give']
    size_receive = request.form['size_give']


    doc = {
        'name':name_receive,
        'address':address_receive,
        'size':size_receive
    }
    db.mars.insert_one(doc)


    return jsonify({'msg':'저장완료!'})


@app.route("/mars", methods=["GET"])
def mars_get():
    return jsonify({'msg':'GET 연결 완료!'})


if __name__ == '__main__':
    app.run('0.0.0.0', port=5000, debug=True)

이건 새터미널에서 실행 눌렀을 때 터미널에 나온 내용인데, winerror가 뭔지 모르겠네요 오류인건지, 무시해도 될까요?
