Blank page when accessing OC via loadbalancer url

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

Have two OC nodes configured with load balancing. Accessing and logging in through each node’s individual URL works without any issue.
However, when accessing via the load balancer URL, the login page appears, but after entering the username and password, it redirects to a blank page.

Facing this issue after upgrade to UIM 23.4 CU5 form 23.4 CU4

Environment

UIM 23.4 CU5

F5 loadbalancer 

Resolution

Found the setting used in non working load balancer is different from comparing with working load balancer in different envieonment running 23.4 CU4 

Tested changing to the same setting as working LB (source_address), no more 401 unauthorized error.

Previously the non working load balancer was using SSL setting so it keep checking for SSL certificate that cause unauthorized error.
