Webapp on linux 32bit not working properly compiled with 2021 r3.1

Webapp compiled with 2021 r 3.1 not properly working on Linux 32 bit. The web app starts and running in the server without any error but when you browse the URL, it just waits for ever expecting some data back. If i telnet it connects to the port but dont receive any message back. Its just a simple app with text “hello”. Any one has similar issue?
