ISP like network. Cannot connect between routers

Hello! I'm having trouble pinging the inside of routers and connecting to the web server. I can ping the loopback address 20.0.0.1 from all the devices.

When I run in simulation mode and ping 192.168.1.1 from Server0, the packet reaches the server, but is rejected at Router4 on the way back to Server0.

I can ping 10.0.0.1 10.0.0.2 and 10.0.0.3 from all devices

These are the configs

Router 2:

 

interface Loopback0

ip address 20.0.0.1 255.255.255.255
