thanks for sending the logs

the logs show that before the repro the Linux eth0 interface has an IPv4 address assigned and multiple IPv6 addresses, but after the repro those are missing. The logs don't show WSL deleting those addresses

this points to either Linux itself deleting the addresses or some Linux agent/process deleting them
sorry, unfortunately the current traces don't give us visibility into what in Linux deleted the addresses

@YiHui-Liu , you mentioned "When the amount of data used reaches a certain threshold" - is there a particular network traffic test you are doing or does this happen after regular WSL usage?

thanks

For my case the problem seemed to come from cloud-init tool, which was included in Ubuntu 20 distribution in my case.

This fixed the connectivity issue for me:

sudo touch /etc/cloud/cloud-init.disabled

and then restart WSL.
