Gurux.DLMS.cpp, unable to set up High authentication with Crystal meter

I am trying to connect using CPP sample to Indian meter from Crystal manufacturer,

I am able to successfully connect and read data with Low authentication,
also I am able to successfully connect with High auth from Director application,
but High authentication fails with CPP sample tool:

./gurux.dlms.client.bin -h 192.168.0.14 -p3333 -w -c 48 -s 1 -a High -Paaaaaaaaaaaaaaaa
InitializeConnection

and it just exits

Looks like authentication requests differ in logs above

Source code in GuruxDLMSClientExample.cpp was modified in order to enable encryption,
these lines were added:

CGXDLMSSecureClient cl(useLogicalNameReferencing, clientAddress, serverAddress, authentication, password, interfaceType);
> CGXByteBuffer title;
> CGXByteBuffer key;
>
> title.Set("GRX12345", strlen("GRX12345"));
> key.Set("AAAAAAAAAAAAAAAA", strlen("AAAAAAAAAAAAAAAA"));

> cl.GetCiphering()->SetSystemTitle(title);
> cl.GetCiphering()->SetSecurity(DLMS_SECURITY_ENCRYPTION);

> if (authentication == DLMS_AUTHENTICATION_HIGH)
> cl.GetCiphering()->SetSecurity(DLMS_SECURITY_AUTHENTICATION_ENCRYPTION);

> cl.GetCiphering()->SetBlockCipherKey(key);
> cl.GetCiphering()->SetAuthenticationKey(key);
