No more able to install add-ons

Until now (yesterday) I’ve installed several add-ons, the latest was Node-Red, now I’m unable to install any add-ons even from the oringial or community repository.
Tried to increase the size of the disk of my virtual machine but nothing…no luck.
Simply the round spinning circle over the install button disappear and nothing is installed.
This is my log:

18-11-21 16:20:23 INFO (SyncWorker_1) [hassio.docker.interface] Pull image homeassistant/amd64-addon-rpc_shutdown tag 0.3. 18-11-21 16:20:39 ERROR (SyncWorker_1) [hassio.docker.interface] Can't install homeassistant/amd64-addon-rpc_shutdown:0.3 -> 404 Client Error: Not Found ("no such image: homeassistant/amd64-addon-rpc_shutdown:0.3: No such image: homeassistant/amd64-addon-rpc_shutdown:0.3").

Any ideas?
