Did you also try ‘Disable Traffic Analyzer’ as this is known to drop large, steady uploads.
Is IPv6 disabled on the XT8 and lastly, turning ON Adaptive QoS as this automatically DISABLES NAT Acceleration.
Reboot and try again (for testing purposes).
FWIW: Your logs as I hinted earlier, the connection is being attempted but there’s no log of a successful upload or TLS handshake. completion.
This is symptomatic of the router dropping long-lived TCP/TLS sessions which means the router interrupts the connection before upload completes and its a case of trying to see what aspect of your XT8 is causing this ?
I just noticed, that you might be using Wifi from the Primary XT8, is that correct and if so, try via LAN, just for testing ?
