Hi,

anybody else having issues when downloading gradle e.g. via

[https://downloads.gradle-dn.com/distributions/gradle-5.2.1-bin.zip](https://downloads.gradle-dn.com/distributions/gradle-5.2.1-bin.zip)

In my case, the browser shows me the finger and tells

> [downloads.gradle-dn.com](http://downloads.gradle-dn.com) uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC\_ERROR\_UNKNOWN\_ISSUER
