Hi Everyone,
I have done with my background IDS configuration. Then try to integrate IDS with frond-end, for that I have set the isIDSEnabled is “true”. Once done with this changes, I have tried to run the UI at that time I have facing this issue in console once loading the UI.

Hello @GeethaNagarajan , Are you using the **“Allow CORS: Access-Control-Allow-Origin”** browser extension? Please confirm.

Hi @Sam, Yes Now using the CORS browser extension. That third-party Api access issue resolved. But still facing this issue. And I want to mention one note here - " In my backend I have changed the default port into 4500 instead of 8081. Because in my system, 8081 always engaged couldn’t use that port. So I changed, is this any chance to issues happened?

Hello @GeethaNagarajan ,
Could you please go to the **middleware section** in your backend, click on **CORS** , and check if it is enabled? If it’s already enabled, there should be an option to edit. After clicking that, just add your **localhost API** there and try again.
Hope this helps!

Hi @Sam, still facing the same issue. while redirecting to Neutrinos login page, automatically it takes 8081 port.
See the below image login api url still localhost:8081-\>

Hello @GeethaNagarajan , It looks like your frontend HTTP node is calling port **8081**. Please try changing it to your backend port **4500** and let me know the result.

Hello @GeethaNagarajan , on the client side, there’s an option in the sidebar called _Environment_. Inside, you’ll find a key–value pair for the SSD URL, which you can update from there. I hope this helps. Please let me know if the issue still persists.
