Cisco Router "Problem"

Heyo Reddit!

For my homelab I use a Cisco 2911. I have a ROAS configuration.

Trunk ports, everything works perfect. Great!

I come back to my workstation and suddenly I can not route anymore. I ping my gateway and its good. I ping my servers gateway and no luck (I should be able to ping, no ACL's are set)

Background:

Server Network - 172.21.4.0 /22

Client Network - 10.0.0.0 /24

The Problem -

The route works originally, but after X amount of hours and the route is broken. The route is still in the routing table. The trunk is fully functional between Switch and Router.

This has had me through a loop for a week now and I am lost for a solution. Ideas?

If I am missing any information to help, ask!
