Hi,

I have change the high level authentication using following code

GXDLMSAssociationLogicalName gxdlmsAssoLogicalName = new GXDLMSAssociationLogicalName();
gxdlmsAssoLogicalName.AuthenticationMechanismName.MechanismId = Gurux.DLMS.Enums.Authentication.High;
gxdlmsAssoLogicalName.Secret = ASCIIEncoding.ASCII.GetBytes("XXXXXXXXXXXXXXXX");
gxdlmsAssoLogicalName.UpdateSecret(dlmsClient);
grxComm.Write(gxdlmsAssoLogicalName,7);

after that , we are unable to connect to meter using the new and old password.

Showing following error on execute ParseApplicationAssociationResponse
"Access Error : Other Reason."

Note: But the same process working fine for HPL meter.

Please let me know what may be wrong on my side.

Regards,
