TCP ping returns always Alive

[xmacan]

It was mentioned in forums. Set device down detection to TCP ping on any port like 3389. Gui shows device up correctly. Spine detection seems to be ok too: 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] DEBUG: Device[1081] HT[1] In Poller, About to Start Polling 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] Device[1081] DEBUG: Entering TCP Ping 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] Device[1081] INFO: TCP Device Alive, Try Count:1, Time:0.2749 ms 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] Device[1081] HT[1] Device has no information for recache. 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] Device[1081] HT[1] Total Time: 0.0013 Seconds 2024-05-21 13:26:28 - SPINE: Poller[1] PID[51831] PT[35179172608] DEBUG: Device[1081] HT[1] DEBUG: HOST COMPLETE: About to Exit Device Polling Thread Function

Change port to any non-opened port. Gui show device down correctly.
