Ipv4 in ipv6 tunnel is not working

Installing and Using OpenWrt Network and Wireless Configuration
1

I have configured an IPV6 tunnel using openwrt, but only IPV6 can communicate and IPV4 cannot be connected from either the router or the LAN.
There are also many logs saying ip6_tunnel: ipip-wan4 xmit: Local address not yet configured.

How did you configured the tunnel? Please share the config.
Also, the message indicates you are missing an ipv4 address on the tunnel?

The following is an example of BR address, ipv4, and interface. The proto of the network wan is ipip6, ipv4ifaddr is xxx.xxx.xxx.xxx (global ip), ipv6addr is ::xxxx:xxxx:xxxx:xxxx (::+interface id), tunlink is wan6, peeraddr is xxxx:xxxx:xxx:xxx::65 (BR address). mtu is 1460. wan6 is dhcpv6, reqaddress is try, ra,dhcpv6,ndp are relay, and suffix is ​​::feed.
ipv6 is online but I can't access the network using ipv4
