Sample UCP AM client failing with error "Destination is unreachable" for localhost

[PrateekJoshi]

Hi, I'm learning UCX by creating a basic wrapper for both the client and server. I am using AM communication. When I run my client, I get below error :

[1749297901.816001] [prateek:19822:0]       wireup_cm.c:128  UCX  DIAG  client ep 0x74059a9e0000 failed to connect to 127.0.0.1:9090 using tcp cms

FILE: /home/prateek/Workspace/UCX/src/client/client.cc FUNCTION : ErrorHandlingCb LINE : 65 message: Error handling callback invoked with status: Destination is unreachable

My code is very similar to sample client-server example in opneucx repo. Below is my code for client and server :
https://github.com/PrateekJoshi/UCX/tree/master/examples

Can anyone help to understand what is the problem ? I will appreciate any help that can lead to fixing this issue 🙏
