I'm sending a heartbeat(ping) back to the server - Sierra logs confirm that - but it doesn't register as a heartbeat and times out after 60 sec. Data flows to the client fine. I have the null terminator at the end of the json as well. (PHP) $msg = '{"Type":3}'."\0"; $conn2->send($msg); DTC Protocol server | Incoming connection from 10.70.70.72. | 2022-12-16 05:23:09.976 DTC client #37. 10.70.70.72 (4) | Creating socket. | 2022-12-16 05:23:09.979 DTC client #37. 10.70.70.72 (4) | New receive buffer size: 262144 | 2022-12-16 05:23:09.979 DTC client #37. 10.70.70.72 (4) | Allocated send buffers: 32 of 131072 bytes. | 2022-12-16 05:23:09.980 WSServer | DTC client #37. 10.70.70.72 (4) | Start Server | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Switch to HANDSHAKE | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Switch to READY_DATA | 2022-12-16 05:23:09.981 WSServer | DTC client #37. 10.70.70.72 (4) | Response HANDSHAKE with status code 101 | 2022-12-16 05:23:09.981 JSON data: {"Type":1,"HeartbeatIntervalInSeconds":5,"TradeMode":1,"Username": xxx"Password": "xxx","ClientName":"trades"} | 2022-12-16 05:23:09.985 DTC client #37. 10.70.70.72 | Requested heartbeat interval: 5 | 2022-12-16 05:23:09.987 DTC client #37. trades. 10.70.70.72 | Received logon request. | 2022-12-16 05:23:09.987 DTC client #37. trades. 10.70.70.72 | Sent successful Logon response message to client.
