the+request+failed+with+http+status+407:+proxy+authentication+required How can I do???

I have used eM Client for a while and for free…but since two hours the license have expired…
When I try to activate, this message is shown: “the request failed with http status 407: proxy authentication required”
What can I do?? Thanks in advance

Hi José, eM Client unfortunately does not support proxy authentication, unless you’re using windows credentials for authentication with your proxy server.

If you’re using windows credentials, download this eM Client configuration file, and move it into your eM Client installation folder.

If you’re using a different authentication method, you might not be able to use the application, while using the proxy setup.
