pgAdmin is not redirecting to /browser

Hello,

for the first time, I was installed pgAdmin4 on RedHat server with apache httpd web server.  when I launch the application and run url https://localhost/pgadmin4, it loading login page and when I entered valid credentials it taking me to https://localhost or apache test page instead of redirect https://localhost/pgadmin4/browser/

after authentication completed if entered manually, this link https://localhost/pgadmin4/browser/ in the same browser pgAdmin is working fine.

Is it a bug or a behavior like this. Does anyone face the same kind of issue?

pgAdmin4 version: 4.21.

Thanks,
Naga
