Issue/Introduction

1. On Project Tile component, error shows
An error occurred while saving preferences.

2. Clicking on a Project, error:
Could not update project preference

Resolution

Check if other nodes can be accessed directly. 
If so, this is an issue with the load balancer settings/rules.

To confirm, obtain a browser trace and review the request/response header.
In one case study, 

Request Header:
PUT /ppm/rest/v1/private/personalizations/5041003 HTTP/1.1

Response Header:
HTTP/1.1 405 Method Not Allowed
Allow: GET, HEAD, OPTIONS, TRACE

Contact the internal team to review the load balancer as per the HAR file/error 405, it only allows the following functions: GET, HEAD, OPTIONS, TRACE,
but not PUT.
