discogs: "error connecting to server"

Hello all

I can't fix a problem: all web services work, except discogs. when I try to access it, I get a "error connecting to server: www.discogs.com". Now the weird part: discogs and discogs direct artist don't work, but the discogs search by album works just fine.
Any ideas?
I'm using 2.39p and all latest scripts.
Thanks a lot!

I'm so sorry, I've posted to the German section by mistake.
