Issue/Introduction

 After installing new performance center i am trying to access the URL where it gives me password expiration and update new password. once i change the password and try to login using new password it redirect me again to login page without any error. 

 

So basically after changing default password and loggin in by new password it redirects again to login page.

 

Environment

Release : 21.2.12

Component : Performance Management Upgrades

Cause

/etc/hosts has a host entry in upper case

Resolution

Access the URL using upper case letters then it will  work

If you want to have the hostname in lower case then updated the /etc/hosts file in lower case.
