Hi, we had a user email us who has a link to a file in Galaxy which the UCSC Genome Browser cannot open because the [usegalaxy.org](http://usegalaxy.org) web browser doesn’t support byte range requests:

track name=“6hr Veh 1” type=bigWig bigDataUrl=[https://usegalaxy.org/api/datasets/f9cad7b01a47213550329ab30779cd1d/display?to\_ext=bigwig](https://usegalaxy.org/api/datasets/f9cad7b01a47213550329ab30779cd1d/display?to_ext=bigwig)

leads to:

**Couldn’t open [https://usegalaxy.org/api/datasets/f9cad7b01a47213550329ab30779cd1d/display?to\_ext=bigwig](https://usegalaxy.org/api/datasets/f9cad7b01a47213550329ab30779cd1d/display?to_ext=bigwig)**

I’m pretty sure that it used to be possible to load Galaxy-hosted files into the UCSC Genome Browser. Is there something that has changed on your end?

Hi @Maximilian_Haeussler – we have added in a change to restore the prior functionality. This is available at [UseGalaxy.org](http://UseGalaxy.org) so far, and the other usegalaxy.\* servers will be updated soon.

Details [HEAD and byte-range support · Issue #14982 · galaxyproject/galaxy · GitHub](https://github.com/galaxyproject/galaxy/issues/14982)

**Update 11/11/2022**

We identified a change that appears to be on our side triggering the import issue. It was likely introduced in the last release. Details are in the public chat here [You're invited to talk on Matrix](https://matrix.to/#/!NhNWKNcgINoFZdbUbY:gitter.im/$NKCRGmOj0OSiqnvBrsOCtsu6fyrgx7Vy-ODmjvTQWRg?via=gitter.im&via=matrix.org)

Happy to be wrong about this method “not ever” working 🙂 We’ll post updates back here, and feel free to follow or join the chat. You can also message me directly to coordinate end-user communications around the anticipated fix when the time comes.

Thanks Max!

Hi @Maximilian_Haeussler

I saw that thread at the UCSC forum, too. Unless something changed very recently, hosting files from Galaxy to the UCSC browser should definitely still be possible.

As a guess, I think the problem with the particular file the user was asking about is that it didn’t have a “database” key assigned. It didn’t have one when I upload it here yesterday (seems Ok to post since is already public data, and I’ll unshare/purge in a day or two): [Galaxy](https://usegalaxy.org/u/jen/h/test-bigwig). A matching `database -> dbkey` is required for the UCSC link to even show up in Galaxy, so how that error was produced wasn’t clear.

Oh! I reread the post at UCSC. This part has clues:

> The Url links to my workspace in Galaxy, where my bigWig files are saved. When I click Submit, the genome browser gives me the following warning:

Maybe the user isn’t linking directly from inside Galaxy, and instead trying to upload the file to the UCSC browser by URL? I forgot how that works on your end – do users target a specific dbkey/assembly for upload? That never worked from what I remember. People had to start in Galaxy and use the link inside a dataset that points to UCSC.

I will still take another look. More feedback, probably tomorrow.
