Switch can't ping a host

Hello, 

I have a switch with Vlan 1 192.168.10.2/24 , there is a host (192.168.10.10/24) connected to the switch. 

I tried to ping like these: 

Host pings VLAN --> Successful

Switch pings host --> Fail

(I tried these on real equipment)

 

I tried to replicate this on Packet Tracer, the same configuration and Switch can ping host. 

 

Can you help to spot the error?

 

Here is the log I got from the Switch: 

 

Switch#debug ip packet detail
IP packet debugging is on (detailed)
Switch#ping 192.168.10.10
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.10, timeout is 2 seconds:

Hi Pieterh,
You save my day, I spent hours just to figure out this. I am so dumb :)
Thank you!
