InternalServerError: No connection could be made because the target machine actively refused it

Code (in C#) has been running successfully each working day since July 2020. Today I had to recreate my Windows User Profile and now my code won't run. Any ideas?

Full error message is: "InternalServerError: No connection could be made because the target machine actively refused it 127.0.0.1:36036"

Please note:

I am running Eikon desktop (not web app) and am logged in
I checked the API key which is unchanged from that which is in my code

@m.ward

You can verify if the API Proxy is running by accessing the following URLs via a web browser.

The output looks like this:

If you can access those URLs, you can specify the TPC port used by the Eikon Data API .NET by using the following code.

eikon.SetPort(9060);

Hi @m.ward and @smajumdar1

Can you please try restarting your machine and Eikon Data API then retry running the code again and please tell us if the issue still persists?
