I work with many open SSH sessions (at least six using tmux). After a few hours, the sessions to IPv6 addresses are dropping. The ones to IPv4 are not.
I am able to confirm that I have lost all IPv6 connectivity using the site Test your IPv6.
Using ipConfig, I see that the Lease is valid (the below was run at Wednesday, February 3, 2021 9:54:05 AM)

Note: I slightly changed the above by replacing much of the IPv6 address with the text <MASKED>
If I disconnect/reconnect (via windows "Internet Access") it regains IPv6 connectivity , but this is annoying and insufficient because I've lost my SSH sessions.
I can usually regain IPv6 connectivity with the below (I can't certify that this works 100% of the time), but this is also annoying and insufficient because I've lost my SSH sessions.

Note that both cases, neither IPv4 NAT address or IPv6 address changes.
I also have a note to the WiFi Router vendor (TP-Link / Archer AX21 v1.20), but because it can be fixed by locally running 'ipconfig /renew6', it seems to be a problem on the Windows side and renewing the IPv6 address.
Any ideas on how to solve this?
Thanks!
