IPIP Routing broken after 7.1 upgrade

Wed Dec 08, 2021 12:24 pm

I have had an IPIP Tunnel with IPSec encryption to a remote location active for more then a year now. This worked perfectly fine until I upgraded my side to RouterOS 7.1 yesterday.
The Tunnel is still active, but the routing is broken which was working fine before.

I can now only ping the remote side when explicitly selecting the IPIP Tunnel interface as "ping interface". When I try to ping the same IP from my LAN bridge it will give me timeouts.

Does anyone know what change in RouterOS 7.1 might have caused this?
Below I have printed the Interface, IP Addresses and IP Routes.
I also noticed that all the Route Nexthops are marked unreachable in Winbox (see attachment).

If anyone can get me up and running again that would be great.
