I have repaired my installation, cleared by microsoft edge cache, and nothing change. I am able to go to pluginstore.sketchucation.com through a browser, so I don't think it is blocked. any more ideas?

This used to work until recently (maybe a month ago?) and I haven't reinstalled sketchup since then. (Although I got a new filter on my computer around that time, but I don't remember what happened first, the filter or the unzipping problem)

I am having the same problem, I have updated the plugin store, but it does not help. I am able to manually download plugins install them, however.

It is working fine now, thanks.

I am also having this problem. any ideas?
