Dear Toni,
Thank you for using the UCSC Genome Browser and Track Hubs and sharing this issue you were experiencing on the genome-euro mirror.
The hub should work now, it looks as though there was a momentary issue with the genome-euro site attempting to connect to one of the files in the hub, specifically the genomes.txt file. Unfortunately when using the &hubUrl= feature to directly load the hub on hgTracks, an error message was not displaying about the connection issue to the genomes.txt file. By going directly to the "My Hubs" tab of the Track Hub page connection page,
http://genome-euro.ucsc.edu/cgi-bin/hgHubConnect, I could find a displayed error message like the below:
By clicking the "Retry Hub" button from
http://genome-euro.ucsc.edu/cgi-bin/hgHubConnect your hub connection then was resolved and it worked. It is unclear why genome-euro was having an issue connecting to the genomes.txt file, while the genome site was not having that problem. This silent error issue on hgTracks when using &hubUrl= has been noted to consider alternative ways to notify users of such connection issues.
Thank you again for your inquiry and using the UCSC Genome Browser. If you have any further questions, please reply to
