I have rented an Aliyun server and want to deploy a blog, but I can connect to Mongodb remotely (my own computer is not a server). If I can"t connect to the server locally, I can connect to it 
.
 CVM system: Ubuntu 16.04 64-bit 
 mongodb.conf Code 
dbpath=/data/MongoDB/blog
logpath=/data/MongoDB/log/mongodb.log
logappend = true
port=27017
fork=true
-sharpbind_ip=127.0.0.1
 remote connection error message 
connecting to: mongodb://xx.xxx.xxx.x:27017/blog
    2018-12-28T10:43:34.335+0800 E QUERY    [js] Error: couldn"t connect to server xx.xxx.xx.x:27017, connection attempt failed: NetworkTimeout: Error connecting to xx.xxx.xx.x:27017 :: caused by :: Socket operation timed out :
    connect@src/mongo/shell/mongo.js:257:13

    exception: connect failed
 I have seen many remote connection methods on the Internet, but only the local connection has been changed, the profile service has also been restarted
