No network - dhcpcd only tries ipv6

Recently I started having network problems with my lan. It seems that dhcpcd only tries getting ipv6 addresses and not ipv4, and I have no idea how to tell it to try also ipv4.
That's my dhcpcd output:
[root@arch-lap ~]# dhcpcd -B eth0
dhcpcd[2515]: open_control: Connection refused
dhcpcd[2515]: version 5.5.4 starting
dhcpcd[2515]: eth0: sending IPv6 Router Solicitation
dhcpcd[2515]: eth0: sendmsg: Network is unreachable
dhcpcd[2515]: eth0: broadcasting for a lease
dhcpcd[2515]: eth0: carrier lost
dhcpcd[2515]: eth0: carrier acquired
dhcpcd[2515]: eth0: sending IPv6 Router Solicitation
dhcpcd[2515]: eth0: sendmsg: Network is unreachable
dhcpcd[2515]: eth0: broadcasting for a lease
dhcpcd[2515]: eth0: carrier lost
dhcpcd[2515]: eth0: carrier acquired
dhcpcd[2515]: eth0: sending IPv6 Router Solicitation
dhcpcd[2515]: eth0: sendmsg: Network is unreachable
dhcpcd[2515]: eth0: broadcasting for a lease

And my ifconfig:
[root@arch-lap ~]# ifconfig
eth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500  metric 1
        ether 00:24:21:62:d5:d3  txqueuelen 1000  (Ethernet)

Re: No network - dhcpcd only tries ipv6

The "eth0: sending IPv6 Router Solicitation" message just means that it's also trying to discover ipv6 routers on the link; not that it's only using ipv6.

Would it be possible to try dhclient instead and see what you get as a results with that?
