Gateway State is "unreachable" in RouterOS 7

I’m having a lot of difficulty getting RouterOS v7 to get the Gateway State to become reachable. I’ve simplified the router config to the bare minimum, it simple pulls an IP address from the DHCP server.

I’m pretty new with MikroTik, and I’m hoping this is a simple problem to solve.

[admin@MikroTik] > /export
# sep/06/2020 17:52:30 by RouterOS 7.1beta2
# software id = xxx
#
# model = RB952Ui-5ac2nD
# serial number = xxx
/interface wireless
set [ find default-name=wlan1 ] ssid=MikroTik
set [ find default-name=wlan2 ] ssid=MikroTik
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/ip hotspot profile
set [ find default=yes ] html-directory=flash/hotspot
/ip vrf
add list=all name=main
/ipv6 settings
set disable-ipv6=yes
/ip dhcp-client
add disabled=no interface=ether3
/system clock
set time-zone-name=Europe/Lisbon
/system package update
set channel=development

Screenshot is attached showing the state of the next hope (gateway state is “unreachable”). I couldn’t find that information on the CLI, hence the screenshot.

This configuration works just fine on RouterOS 6 (the gateway state becomes “reachable”), and it’s a pretty simple configuration, but I think I just lack the knowledge to know what I am missing.

FWIW - I got a long way down the road to creating a wireguard tunnel, but had routing problems once it was setup. Neither router could route beyond their own interfaces, I think because the gateways were seen to be unreachable. I paired the config back to the minimum to hopefully make diagnosing easier.

There is no ip/nexthop menu in ROS v7.
Instead you can check forwarding path: /routing/forwarding-path/print
