No Plugin Updates available

Hello everybody,

I want to install the sen2cor plugin in SNAP. I installed the standalone installer, but if I remember it’s necessary to install the plugin in the application, too. Evertime I want so check for new updates or search for available plugins this message appears: Unable to connect to the SNAP Community Extensions because of Server returned HTTP response code: 403 for URL: https://step.esa.int/updatecenter/6.0/snap-community/updates.xml.gz

How can I install and update the sen2cor plugin and others?

We updated the server and are facing some issues. We are working on it and hope to fix this soon.
Please see this post too:

Server maintenace still ongoing

Dear SNAP users, as you probably already noticed we are currently updating the server and the server software of the STEP website and the forum for a better performance and user experience. Unfortunately, problems occur during the updating phase. We are working on the remaining issues, like problems with GitHub login, failing updates or the download of auxiliary files (DEM, water mask, etc). We beg for your patience and apologise for the inconvenience. The SNAP Team
