Quote the URL argument properly. These
[1] 10869[2] 10870 lines indicate that the shell runs something in the background and this is because of unquoted & characters. You definitely don't want to run it this way as you lose some parts of the URL (they form harmless(?) pieces of shell code interpreted by the shell). Your URL does not contain single-quotes, so just single-quote the whole of it. Quoting won't probably solve your problem, still it's the right thing to do.
