Juniper Logs do not receive to Graylog

Hi guys
I run a graylog server with two IP addresses in separate VLANs (Local VLAN and Management VLAN). I created a Global Raw Plaintext TCP Input to get logs from Juniper with the following configs:

Bind Address :
Port: 12201
Receive Buffer Size : 1048576
Maximum message size : 2095172

but i don’t get any log from juniper. When i verify packets with tcpdump on management interface on Graylog server i saw the following is repeated continuously > Flags [.], cksum 0x1899 (correct), seq 1239593:1240973, ack 1, win 63335, length 1380 > Flags [.], cksum 0x8bea (incorrect -> 0xb31b), ack 1234073, win 65084, length 0 is Juniper IP Address and is Graylog Server IP Address.

Graylog Server : Centos 7 and Version 2.4.6

Please help me! what’s your idea?
Best Regards.

I find solution!
Null Frame Delimiter must selected.
