Two locations, two RB3011, tunnel connection problem

Hi all.

I’m having a problem connecting a NAS server with a network drive (SMB) between two locations, with two microtransit machines hooked up with IPSec.
I have a tunnel set up between the local Mikrotik networks, I also have basic routing, NAT, firewall. To my eye - everything is configured correctly. Despite this, Mikrotik 1 does not ping the LAN of Mikrotik 2 and vice versa.
Of course, I will pull and post the configuration here if you point out to me what to pay attention to.

Thank you very much for any help.
