Ipv6 not working corectly

[Ramazik]

I set up a connection to Cloudflare WARP where I use the IPv6 server address. The connection works fine in the first seconds of connection. After a successful connection, literally from the 16th second the connection stops working and the traffic counter starts showing unreal numbers in gigabytes. My physical connection cannot afford this at all. For example, in my screenshot for 56 seconds the outgoing traffic shows 1.94 GB (an obvious error), and the incoming traffic 347.69 kilobytes (closer to the truth)
