Run keycloak on 32 bit Linux for SSO

Hi all
I am trying to set up LDAP with keycloak on Raspberry pi using Ubuntu server 32 bit to implement SSO.
I could not connect to localhost:8080 via browser but when I repeat same on ubuntu 20.04 64 but Linux, I can access it. Does Keyclock not support 32bit Linux for SSO?
please guide
