My Chromebook has just updated to Version 119.0.6045.214 (Official Build) (64-bit) and once again can't connect to Sky Qbox.
This year every time the Chromebook updates this happens and none of the suggested solutions work, it is just a case a waiting many weeks for it suddenly to connect, it then works till the next update.
Only two weeks ago I spoke to someone at Sky from the Sky Go app team but don't think they really understood the issue and thought I couldn't log in, when the issue is connecting to the box. I am on the same wifi, got multiscreen etc etc.
So to previous posts with the same/similar it seems to be a common issue that really needs looking into as it is not our devices it it the apps issue.
