Ipv6 used to work on my network with my flint router, but I've had it disabled for a few months now. When I turned it back on, it never assigned an ipv6 address. I tried contacting my ISP and they confirmed that everything looks good on their end and did some troubleshooting, which didn't help. Is there anything I can try with the router apart from a reboot? I use adguard home and I have vnstat2 installed, but I don't use wireguard or anything else. It's running the latest stable firmware.
Ipv6 is set to native with automatic dns acquisition.
