Not able to read data and no error message Gurux Python

Hi

Im using Gurux.DLMS.python to connect meter

using ipv6 protocol

im able to connect using GuruxDirector, but when i connect using python with same parameters using Gurux python Im not getting any output, It just gets stuck

I m using
python main.py -h 2402:3A80:1702:106::1 -a High -P asciixxxxxxxxxx -C AuthenticationEncryption -p 4059 -d DLMS -W 1 -T hexxxxxxxxxxx -A hexxxxxxxxxxx -B hexxxxxxxxxxxx -L TIS -s 1 -c 30 -l 0 -t Verbose -i WRAPPER

Am I missing anything.?

Edit:

I go this error msg

gurux_dlms version: 1.0.121
gurux_net version: 1.0.18
gurux_serial version: 1.0.18

KeyboardInterrupt

root@localhost:/var/www/gurux/Gurux.DLMS.Python-master/Gurux.DLMS.Client.Example.python#

Later i changed gurux_net module GXNet.py to useIPv6 = True and

in Network.TCP else

self.__socket = socket.socket(self.__getInet(self.__host_name), socket.SOCK_DGRAM,0)
print(self.__getInet(self.__host_name),self.__port)
self.__socket.connect((self.__host_name, self.__port,0,0))

So now no error but no reply also
