Dear Mugen-Team,
Sadly our internal repository or the application have maybe a problem.
We are all getting ERR_BAD_REQUEST errors when we try do download medias from our repository since about a week.
We are using v8.0.83-master on our clients (mac os & windows).
Thanks and best Regards,
Niklas
First and foremost this isn’t a KM Server issue because we haven’t updated it lately.
Have you tried using an older version of KM 8? Like one the week before or so ?
The Songs are definitely accessible via the webui, so the song should be available for download.
We have tried it with an older 8 version, same error there.
I see, that there may be a uuid migration that not completely done, that may be the error here. We will look into that and report again! 
Ah
That might explain why @Themio asked that the other day.
I was going to ask for a full log but yeah.
Fixed from Themio 
It was the UUID migration.
Thanks for the quick response!
Have a nice evening!
No problem, glad it was fixed.
