Melanjutkan thread ini pak

Hasilnya ping dan trace nya  normal pak, tidak ada yang mencurigakan.

Mengenai error yang muncul
'Socket error sending response to DATA'
'*  Winsock Error 10060 The connection timed out'

Apa kira2 yang bisa saya lakukan dari sisi koneksi di sisi ISP masing2 pihak
pak?
Karena dari sisi sender mereka keberatan untuk menambah idle time nya di
server mereka

Berikut saya capture error yang terbaru:
