Reactor.core.exceptions$reactiveexception: java.net.Unknownhostexception #588
Description
Hi guys,
We're having trouble with accessing the properties of our storage services. We're getting java.net.Unknownhostexception every time trying to reach the endpoints of services (this happened with fileShare, table, queue, and blob). I did try an nslookup from the command line, the storage account endpoint seems to resolve just fine.
The storage account we're having trouble with is the kind Standard General Purpose V2 (StorageV2) which does support 4 kinds of storage services but the exception was still thrown:
