Based on the configuration and output the following test is failing:
ping 192.168.32.22 source 192.168.32.21
You will need to find what is wrong on either the network or SRX configuration that the ping can no longer take place.
Run this on the cli and confirm this does not work.
Confirm the source address is a valid address on the SRX that can be used (should give an error on the ping attempt if note)
Run a trace route to see where the path to the device dies
traceroute 192.168.32.22 source 192.168.32.21
