I've been having this issue for quite some time and can't seem to figure out what the problem is. It may be on DOGnzb's side but not sure. Basically, when searching for anything I get the "Error loading Items" or "No Results Found" error like 9 out of 10 times. If I continuously keeping hitting the search it will eventually load the results. I've verified all the settings are correct as far as I can tell (and I think they are as it does return the results eventually). I've tried changing my API but that didn't fix it. Any ideas on how to correct this?

It's on Dog's side. Their API performance is quite poor. I'd send a note to them about it. The more they know their users are upset and experiencing this, the more they might act on it.
