Scanning doesn't give the result

[LaRevoltage]

I am using 6to4 to scan ipv6 adresses, using nmap i can scan adress, and get info that port 80 is opened, but masscan says that nothing is found Here is ip -6 addr output: root@SC219-S33:~# ip -6 addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1000 inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000 inet6 fe80::529a:4cff:fe68:a8b6/64 scope link valid_lft forever preferred_lft forever 7: tun6in4@NONE: <NOARP,UP,LOWER_UP> mtu 1480 state UNKNOWN qlen 1000 inet6 2002:5ee8:2d97::1/16 scope global valid_lft forever preferred_lft forever inet6 ::94.232.45.151/96 scope global valid_lft forever preferred_lft forever

masscan -p80 2607:f8b0:4020:805::200e -e tun6in4 --src-ip 2002:5ee8:2d97::1 --rate 100000000 It print 0 found, but nmap print 80 port. What is wrong?
