Download Request failure, Client Machine sending FIN, ACK - [RESOLVED]
Good day, everyone.
One of our customers is presenting a peculiar issue and I can't pinpoint the root cause.
They have a Citrix Netscaler (10.76.0.74) that acts as a load balancer (10.76.0.95) for 2 web gateways (10.76.0.93, 10.76.0.94). Those web gateways, by default download any files requested to themselves and scan them, before sending to the client machine (10.76.6.0/23).
Please see diagram on the link below for clarification.
When requesting a large download file, the client machine seems to send a FIN, ACK, timing out the connection and canceling the download.
Initially, I thought the what was sending the FIN, ACK was the Netscaler, not the client machine. I opened a ticket with Citrix, and a skilled but not-so-helpful engineer after reviewing the logs pointed out that the Client Machine sending the FIN, ACK.
Please access the following link for files and screenshots: https://trilogytechnologies-my.sharep...
I'm only starting to get around networking, so I'm a bit lost on how or why would a Client Machine send a FIN, ACK on a download request; even more when we bypass the Netscaler/Web Gateway, the download completes.
Am I missing something here or is it actually the client machine timing out the download cycle?
Many thanks,
Caio
