I just upgraded from MongoDB 3.2 to 3.4.1.
/etc/mongod.conf had a multiple BindIP:
bindIp: [127.0.0.1,192.168.20.1]
This is not working anymore. I get this error :
Scalar option 'net.bindIp' must be a single value
According to the documentation, It must be correct : https://docs.mongodb.com/manual/reference/configuration-options/#net.bindIP
Any idea ?
