Hostname wireguard prob

Installing and Using OpenWrt
1

Been using wireguard on openwrt sometime now. Almost all is working except for endpoint in hostname form. When using ipv4 adress it works, but if I use the hostname the provider has given me it wont connect to the wireguard. Limitation in wireguard on openwrt or my fault?

Most likely the address resolves to both IPv4 and IPv6, with the latter having precedence. You can verify with an nslookup.

spot on! IPv4 and IPv6!

You can use this code in dnsmasq configuration to return empty AAAA responses and regular A.

address=/example.com/::
server=/example.com/#
