Is anyone else having this issue? I have updated server many times.

Yes, same here. It's been happening for a while already. I can say that if I try a few (quite a few) times, then eventually, it gets me results. Unfortunately, it is hit or miss.

I've seen a few posts on this, but so far, no resolution.

I don't have nzbgeek, but if it's 'hit or miss' it just might be server side.

You can analyze the traffic to see if an image returns from the server. If it does, then the issue is with the app.

Is it just the HD subcategory? Is it intermittent?

I have NZBGEEK and I get results every time I search, including Movies\HD.

Did anyone figure this problem out ? it randomly happens to me when using nzbgeek.

I just configured another indexer, oznzb, and searches are instant and work as expected... provider/nzbgeek issue ?
