Description
A DNS name is fully qualified if the name ends with a dot.
We expected that a fully qualified DNS name would work with mongo-go-driver, in the same way that an unqualified name would:
mongodb+srv://internal.mongos-main.svc.svc.our.company.tld./?valid=opts
|
Unfortunately, we get an error in this case:
error parsing uri: Domain suffix from SRV record not matched input domain
|
The SRV record is indeed valid:
; <<>> DiG 9.10.6 <<>> SRV _mongodb._tcp.internal.mongos-main.svc.our.company.tld.

And the driver does otherwise work if we drop the trailing dot.
