i am not a user of packet tracer.

 

high level -

do you have VLAN created in all the switches? by default cisco use default VLAN1 as native VLAN.

so make sure one of the VLAN setups is native VLAN.

 

 

suggestions :

 

 - create another VLAN for the management of the switch

- create a SVI for the management VLAN with a static IP

-  subinterface on the router for the management VLAN

- set the default-gateway of the switch with a static IP (IP of the router subinterface)
