We are not blocking this IP address. I see that you're using port 433, but it should be 443, one digit off.


Best not to use a default port anyway when a scheme such as https:// is specified.


Sorry, the port are 443, not 433

This is an ACME Certificate Authority running Boulder.

This is a programmatic endpoint, an API for a computer to talk to. You should probably be using a specialized client to utilize the service, and not your web browser. See for help.

If you're trying to use this service, note that the starting point, the directory, is available at this URL:

But i have always the error : Failed to parse

Is the letsencrypt program up to date in your system?


Your success with curl shows that this is not an IP communication problem. I suggest you open a new topic and use the template to fully describe your errors.


I Have uninstall letsencrypt and reinstall. Its Work.
Thank You
