Hi!
The problem is not only with Discogs. I am getting the same thing with Freedb. Since Discogs wasn't working Ithought I would use Freedb and just change some of the information... but that isn't possible.

Discogs doesn't even access their database to load results based on your search input.

Here is a Discogs log (search term "artist" beatles):

I am authenticated at Discogs and have been for awhile.

Once again, using the search "artists" beatles, freedb goes one step further than Discogs and brings up a number of albums, but when you click on one of the albums for extra information you get the bad HTTP status message. See log below:

Thanks for looking into this Andrei! It is really really appreciated.
