java.net.UnknownHostException: api.cloudinary.com: unknown error

[pawsaw]

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')

java.net.UnknownHostException: api.cloudinary.com: unknown error at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) ~[na:1.8.0_66] at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:928) ~[na:1.8.0_66] at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1323) ~[na:1.8.0_66] at java.net.InetAddress.getAllByName0(InetAddress.java:1276) ~[na:1.8.0_66] at java.net.InetAddress.getAllByName(InetAddress.java:1192) ~[na:1.8.0_66] at java.net.InetAddress.getAllByName(InetAddress.java:1126) ~[na:1.8.0_66]

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
