Why does R-keeper software not work in a network built on Mikrotik?

Question

network hardware

Good afternoon.
The provider changed and I had to install my own equipment, I settled on Mikrotik.
There are 2 "white" addresses. They sit mikrotik RB2011iL and HEX lite.
2 Mikrotik routers connected using L2TP + IPSec
On the first Mikrotik RB2011iL, an L2TP server was set up. On the second HEX lite client.
The first Mikrotik RB2011iL distributes addresses 192.168.1.0.24, the second HEX lite distributes 192.168.2.0.24
From the computer connected to the HEX lite, they ping to the computer connected to the RB2011iL, it also connects via rdp and passes the telnet connection through open ports.
There was a problem with the R-keeper 7 software.
The "server" is connected to the RB2011iL and has the address 192.168.1.251 , the "client" (checkout) is connected to the HEX lite and has the address 192.168.2.252. The connection fails (Changes made on the server are not reflected on the client side).
Another cash register connected to RB2011iL with address 192.168.1.252 works (picks up changes made on the server side)
On the client side, all settings come down to specifying the server address and port in the .ini file.
[TCPDNS]
RK7SRV=192.168.1.251:3639
The server is pinged, I can access it via rdp, telnet to 3639 also enters.
I just can not understand what the problem is, in the network or in the software?
Please tell me what is the problem?

Yes, you are right, /24 is a mask, I wrote it wrong. Routes are registered on both Mikrotik.
After all, pings go between subnets, or is this not an indicator?
