Gurux DLMS for Java

Hi,

I am unable to make US connection using dlms for java. Gurux director successfully create US connection. So I have compared data of gurux director and dlms java. Both are same. But during parsing of user information, java code giving error as follows:
gurux.dlms.GXDLMSException: Connection is permanently rejected
No reason is given.
at gurux.dlms.GXAPDU.parsePDU2(GXAPDU.java:1111)
at gurux.dlms.GXAPDU.parsePDU(GXAPDU.java:873)
at gurux.dlms.GXDLMSClient.parseAareResponse(GXDLMSClient.java:729)
at le.dlms.client.GXDLMSReader.initializeConnection(GXDLMSReader.java:474)

I am using dlms java version 2.2.22.
I want to know how can i resolve it.

Thanks

Hi,

Check that your client address, authentication level and password are the same.
This is usually the reason.

I have passed correct client address, authentication level and password. Even then i am getting this error.
If i use authentication level high with security level none then it works fine. But when i change security to AuthenticationEncryption then it fails. After decrypt data, i am getting tag 199. which cause to this error from parse(initiateRequest, settings, cipher, data, xml, tag); method in GXAPDU class.
