What I understand is that the included certificates for Python are outdated, and they are not updated when installing a new GRASS version (through the OSGeo4w setup, like for QGIS), since the Python versions might not change. When I reinstalled my computer
with the same versions that had a problem, passing from win10 to win11 on the same day, the problem wasn’t there. </div>
<div>This also caused a problem when trying to download a dataset from the start screen, so you might want to check if you can download a sample location too.</div>

<div>Hello,</div>
<div>we have some problems with addons download in Grass 7.8.6 legacy.</div>
<div>The menù command "Install extension from addon" produce an empty list.</div>
<div>If we try to install extension from command line I obtain this:</div>

<div>Downloading precompiled GRASS Addons <r.diversity>...</div>
<div>ERROR: Cannot open URL: <a href="http://wingrass.fsv.cvut.cz/grass78/x86_64/addons/grass-7.8.6/r.diversity.zip" title="http://wingrass.fsv.cvut.cz/grass78/x86_64/addons/grass-7.8.6/r.diversity.zip">
http://wingrass.fsv.cvut.cz/grass78/x86_64/addons/grass-7.8.6/r.diversity.zip</a><br>

<div>but if I paste the repository addres sin a browser we correct download the zip file of addon, i.e. the addon exist, but Grass can't download it.</div>
