Routers between a switch can't ping eachother

[MangoChocobo]

This is my network i've been playing with in PT. I've got each side (Denver and NYC) to be able to ping Router 2 at the top as well as the PC's. However, my issues is I can't get Denver or NYC Router to ping eachother. Why is that? 



Show runs:

- DEN_Router https://pastebin.com/YG7MAyuz

Any help is appreciated!

Could you show switch0 and routers2 configuration?

Based on the information in the drawing the issue is that the router interfaces f0/0 are not in a common subnet. The addresses given are 192.168.120.33/28 and 192.168.120.65/28. For those addresses to be in the same subnet the mask must be at least /25.

I'll try changing them to /25, This is a project I have at school currently and the router up top is a proxy router to the school's network. so I don't have complete access to this. In my scenario at school, we have some servers and clients and Denver and our main Server is at NYC. In school, I can't get them to communicate with each other but wanted to keep them in separate networks but nat them, but to no avail have I been able to fix this issue

Hello

Can you post the PT file please..

[MangoChocobo]

There you go, I've edited it more on my side and i'm trying to work through it. I can now ping the other router since i've made them part of a /25 network.

Reminder, I don't have access to Router2 or Switch0. 

I had to zip it since .pkt files are not accepted extension to send files on here.
