Hello, I'm fairly new at Cisco and I was making a project with routers and stuff. All of my devices were working perfectly and all the packages were sent completely. After I saved everything and turned the program off I opened file again. Gave it some time to load up everything and not barely something works... All of the stuff like hops, ips and gateways are still in place but it still wont ping... I have no clue why. I will add picture of topology and proof that it was pinging in the all system
