node连接mongodb报错no primary found in replicaset如何解决？

启动gitlab上的fleximanage项目的时候启动失败，报错信息如下：

(node:676369) UnhandledPromiseRejectionWarning: MongoError: no primary found in replicaset or invalid replica set name
    at /root/src/flexiwan/fleximanage/backend/node_modules/mongo-express/node_modules/mongodb/lib/core/topologies/replset.js:624:11

环境信息如下：

1. 系统环境:ubuntu 20.04
2. mongodb版本：MongoDB server version: 4.0.9

3. mongodb集群信息:

       }
   

}

4. mongodb连接串`mongodb://root:root@172.26.218.169:27017,172.26.218.169:27018,172.26.218.169:27019/flexiwan?replicaSet=rs0&authSource=admin`


5. mongodb连接设置` {
    useNewUrlParser: true,
    useCreateIndex: true
  }`

请问有没有大神有思路帮忙看一下？多谢！
