When I use EPG Importer with Rytec's sources there are no problems.
When I use an other source url where the file ends in xml.gz I get the error download failed: [Errno 2] No such file or directory: ...
When I try the same url in a browser a file is downloaded. When I upload that same file to my own server and use that url the same file works in EPG Importer.
The epg provider says the problem must be on my end.
