Hello everyone,
First of all, great community! 
Secondly, I am having issues with my Hass.io instalation (and it seems I am not the only one). I am running Hass.io with HA 0.91.0 and Supervisor version 152.
I have plenty of disk space as you can see here:

I am trying to update to 0.91.3 or to install updates and I can’t. I get this error:
19-04-11 20:00:42 ERROR (SyncWorker_13) [hassio.docker.interface] Can’t install homeassistant/armv7-hassio-supervisor:158 → 500 Server Error: Internal Server Error (“Get https://registry-1.docker.io/v2/homeassistant/armv7-hassio-supervisor/manifests/158: dial tcp: lookup registry-1.docker.io on [2001:8a0:ee99:2800::1]:53: read udp [2001:8a0:ee99:2800:f6cb:46dd:57ac:7d99]:55687->[2001:8a0:ee99:2800::1]:53: i/o timeout”).
This happens for Home Assistant updates and the add-ons. I am connected via Wi-Fi and if I connect the Ethernet cable everything works. The problem is that it is not suitable for me to get a cable to the place where the Pi is.
Anyone can help?
Already tried rebooting hardware and hassio and checked all things stated above.
Thanks a lot!
