Connecting HVAC controller to network

[Luzbel]

I have a network with multiple Cisco 9300 Switches and 9606 Core switches. We had a PC connected directly to a Carrier i-Vu XT Router. The PC needs to be moved to another building. I connected the router to the switch for that building on VLAN 202. The switch connects directly to the core and to the other 9300 switch at the building where the PC was moved to. I have VLAN 202 set on the trunks and on the access ports. The IP address for the PC is 192.68.24.7 with default gateway 192.68.24.1. On the switch where the router is connected I have the following setup for the VLAN interface port:

interface Vlan202
ip address 192.68.24.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip ospf 1 area 0
no autostate
end

The interface configuration for the router and PC are the following:

switchport access vlan 202
 switchport mode access
 spanning-tree portfast
 spanning-tree bpduguard enable
 spanning-tree guard root

I did a show spanning-tree vlan 202 on both switches and the core with the following results:

I am able to ping the router from anywhere in the network except from the PC. I know that the ports that need to be open are UDP 47808 and TCP Ports 80 and 443.

I tried connecting the PC to the main User VLAN to test and although it does ping the router and default gateway, the application doesn't connect to the controller. Moving the switch interface port to VLAN 202 i also changed the default gateway on the PC to 192.68.24.1 to test, but still won't even ping the router.

Not sure what other configuration I need to let the PC communicate with the router.
