For the past week or so Youtube videos fail to load probably 80% of the time. I can see the static image of the video, press play and the circles spin for a few minutes and it just says an error occured. If i hover over the times in the playback bar it shows a thumbnail of the video but doesn't play. This affects any device connected to the Homehub, so iPhone and all PCs. It affects every video i've tried. If i disconnect from the homhub and tether to my iPhone over 4G the videos always work fine.
Everything else like Netflix, NowTV, iPlayer ete are fine.
