My guess is you had a Zone set then did not when you reinstalled ...

It is possible that there was another issue, but so far I am not finding any other trigger for this. I thought your reinstall was the fix also, as the same thing happened for me. But then I realized that I had the Zone set when it was broken and on the new install I did not have the Zone set.

So it was just a dilussion on my testing, making me think a new install fixed it, until I really tested it a lot further for the real issue ...
