CORS Error: Multiple 'Access-Control-Allow-Origin' Values - Troubleshooting Guide

This error message indicates that the server at "http://10.245.181.68:90" does not have the appropriate CORS (Cross-Origin Resource Sharing) configuration. The server is sending multiple values for the "Access-Control-Allow-Origin" header, specifically "http://localhost:8081, http://localhost:8081". To resolve this issue, the server needs to be configured to send only a single value for the "Access-Control-Allow-Origin" header. It should be set to "http://localhost:8081" without any duplicates. Please note that the specific steps to configure CORS vary depending on the server and framework being used. You may need to consult the server documentation or seek assistance from a server administrator or developer.
