Had upgraded our AT instance to AT v0.10.1 and the FW to v4.4.0, however the plugins did not upgrade at that moment, no message or anything else.
Checking the Plugin page of the AT, all plugins were still at the low version.
On advice in the gitter room, I tried to do a downgrade to V4.3.0 and see if they would go. But when doing that, I get a message for all plugins stating : "Failed to install [pluginname], error: Response of request to http://adapt-bower-repository.herokuapp.com/packages/search/[pluginname] is not a valid json.
I tried to go up to v4.4.0 again, down to v4.2.0, but the error persists.
Anyone any thoughts where my problem could be?
