On my old computer, it worked properly, I have the error only on my new computer.


hi, sounds like an HTTPS/SSL error. Maybe you are behind a corporate Proxy/Firewall that does not allow you do download from https://maven.atlassian.com/repository/public .

Or you are on a machine where the CA-CERTS are broken for your Java Virtual machine.

here is a helpful documentation on how to find out the problem:


I hope you can solve your problem :slight_smile:

Thanks for your response!
When I realized it was related to Proxy and Firewall, I did contact the security team at our company and they took care of it thank you!
