XB8 loses internet for 5 to 10 minutes overnight without rebooting (signal fine)

My internet drops overnight for 5 to 10 minutes, but the gateway never reboots. It's an XB8 (CGM4981COM, firmware Prod_24.2_PD).

The two drops I know of were Nov 10, about 3:19 to 3:24 AM, and Nov 13, 2:10 to 2:20 AM, Mountain Time.

During each one the gateway stayed up with 13+ days of uptime, all downstream channels stayed locked, SNR was around 40 dB, there were zero uncorrectable errors, and my public IP didn't change. A wired device on the LAN saw the gateway withdraw its IPv6 default route at 2:10:58 AM and bring it back at 2:20:15 AM, which means it lost its connection on your side. The gateway firewall logged "FW.IPv6 INPUT drop, 29 attempts" at 3:19:25 AM on Nov 10, the minute that outage started. Otherwise the gateway logs show nothing at those times.

Could you check your network and provisioning records for my gateway at those times and tell me what caused it? I run a server that needs to stay connected.
