Tunnel down after upgrade from Linux 5.8.18 to 5.9.8

[jthnetdkeu]

After upgrading from Fedora 32 Linux 5.8.18 to 5.9.8 the tunnel via 216.66.84.46 is down.
I am using this setup

ip tunnel add sit1 mode sit remote 216.66.84.46 local 95.154.24.73 ttl 255
ip link set sit1 up
ip addr add 2001:470:1f14:773::2/64 dev sit1
ip route add ::/0 dev sit1

This command normally not used and makes no difference
    ip tunnel 6rd dev sit1 6rd-prefix 2001:470:1f14:773::/64 6rd-relay_prefix 216.66.84.46/32

ip -f inet6 addr

I can ping6 to my end of the tunnel and 216.66.84.46 but not the remote end of the tunnel 2001:470:1f14:773::1
Firewalld has been stopped

Any idea ?

Hello,
I have the same problem on Fedora 34.
Did you find a solution meanwhile?

Cheers,
