Issue/Introduction

Applied the 20.3.2 patch successfully. When login to OC over Load Balancer URL gives no errors but just returns  to the logon page.

 

Environment

Release : 20.3

Component : UNIFIED INFRASTRUCTURE MGMT

Resolution

Upon examining the NGNIX logs, the request after login was rejected by NGNIX as the header size limit exceeds.  

The login process was failing as NGNIX is rejecting the request because headers (Authorization) sent by the OC is large. The default NGNIX header limit is 4K-8K. We updated the ngnix.conf file with updated configuration as below to support the Header successfully sent from browser --> ngnix --> OC Server.

 proxy_busy_buffers_size   1024k;
 proxy_buffers   40 1024k;
 proxy_buffer_size   512k;
  
After updating the ngnix configuration, as mentioned above, fix the issue enable to access the OC over Load Balancer URL.
