Can someone help me to figure out this ICMP issue

See attached diagram for more info and the config can be found below:

When I ping from R3 to R1 loopback, I get the following error message:

Hi

Have you verified if the R1's loopback has an entry into the R3's routing table? and if the R1's routing table has entries related to R3's networks?
