Eikon python API not working

I'm using the Eikon APY through Pycharm and usually everything works fine but for some reason the API doesn't run anymore, which is strange because Eikon is up and running, up-to-date version of both Workspace (desktop) and Pycharm...?

Thanks for reaching out to us.

It may relate to the following errors:

It looks like this it was unable to resolve the localhost (127.0.0.1) address. According to these errors, you may need to verify the network settings, such as security software, firewall, or proxy settings.

You can also refer to the Eikon Data API and Refinitiv Data Library - Troubleshooting article to make sure that the Eikon Desktop or Refinitiv Workspace is running properly.

I hope that this information is of help.

Thank you for the answer. I hadn't considered our firewall settings :)
