The connection sting parser returns a list of hosts like this:

[

{host: "compass-data-sets-shard-00-02-e06dc.mongodb.net", port: 27017}

,

{host: "compass-data-sets-shard-00-00-e06dc.mongodb.net", port: 27017}

,

{host: "compass-data-sets-shard-00-01-e06dc.mongodb.net", port: 27017}

]

but the initial hostname was compass-data-sets-e06dc.mongodb.net
According to the specification, {{mongodb+srv://

{hostname}

.

{domainname}

/

{options}

}}
for srv connection string it should be a single hostname. The original hostname should be returned after parsing, but it appears to be modified.
