ADA Cloud: SSL certificate update

Dear Users, 

This is to inform you that today, 2 December 2025 between 14:00 and 15:00 we will update the SSL certificate chain to access CINECA HPC Cloud systems via Command Line Interface. 

From this afternoon, you will not be able to use OpenStack CLI with the old certificate. You will need to download the new certificate and load it in your environment using the following command:

export OS_CACERT=<path/to/new/certificate>

or by adding the following line in your clouds.yaml file as follows:

cacert: "<path/to/new/certificate>"

The new certificate will be available on our ADA Cloud documentation page:

Best Regards,  
HPC User Support – CINECA
