Access keycloak with ip after configuring frontendurl

I have added frontendUrl in CUSTOM_JAVA_OPTS. After that keycloak cannot be accessed with ip.

the only accessible url with ip is

which automatically redirects to the frontendurl configured

But is it possible with some configuration to be able to access all URLs with ips after configuring it with frontendUrl ?

In the browser web console the following error appears
