I see this kind of errors in the browser console:  
_I do not know if they are related errors but I share them, just in case…_

a 502 error relative to the `/push-service-worker.js`  
and 500 errors for the `/admin/docker/upgrade`

I tried to click on the start upgrading button when a plugin update had already begun to see what would happen → the upgrade seems to stop (the log disappears, after some minutes it reappears).

But If I click to turn back to the `docker/upgrade/versions` I see this:

and if I click on Currently Upgrading:

 ![firefox_2017-09-29_18-23-07](https://global.discourse-cdn.com/meta/original/3X/8/5/853e1aaca5bde1b11602f495811ea537e58c5326.png)

I can see the disappeared buttons (the log reappears after few minutes, about 3 or 4, at the beginning it remains completely empty).
