While using the JavaSdk (Kotlin in Spring context), I'll get this error. A couple of days ago everything has been working... no code change throughout this time period.

build.gradle: compile('com.cloudinary:cloudinary-http44:1.18.0')

Hi,

Does this happen on image upload? Can you please share your code?
What version of Cloudinary and Java are you using?
Did you experience this issue before?

Hi @aditimadan-Cloudinary

Yes, it happens on upload. Since we're using cloudinary for a month, it doesn't happen before. We haven't changed our code.

The versions are:

com.cloudinary:cloudinary-http44:1.18.0
java: 1.8.0_66

The code (kotlin) is nothing special...

the initialization...

lateinit var cloudinary: Cloudinary

@PostConstruct
fun init() {
    cloudinary = Cloudinary(ObjectUtils.asMap(
            "cloud_name", cloudName,
            "api_key", apiKey,
            "api_secret", apiSecret))
}`

and the upload itself...

cloudinary.uploader().upload(tmpFile, ObjectUtils.emptyMap())

This exception means it has trouble resolving the hostname. Can you try the suggestions mentioned in this link and see if it works: https://stackoverflow.com/questions/6484275/java-net-unknownhostexception-invalid-hostname-for-server-local
