after installing mp3tag, i am sadly facing a problem when trying to use Discogz as a source.
I created a discogz account and under "Settings" --> "Developers" i generated a new Tocen, which is 40 characters long and has alphanumeric characters. It looks like this:
After clicking on discogz in mp3tag, it requests an activation code. After adding this code, it says
"Failed to authenticate using oauth(2)
400: Bad Request"
Am i doing something wrong, is this an known issue?
How to solve this issue?
Mp3tag will open the default web browser with a page on Discogs asking to allow Mp3tag accessing your Discogs profile. Once you've confirmed this, the page displays the access token which is shorter and can be entered in Mp3tag's input dialog.
yes this is correct. Like i stated, the developer code was wrong but i also wrote that the procedure works with Windows 7, meaning that i am aware of the steps i have to take and of the workflow.
Sadly, in Windows 10 no website opens but the error 400 occurs in mp3tag. In windows 7(virtual machine in my windows 10 pc) the website opens and i can confirm the access and will receive a ~8 character long activation code which i can add at mp3tag.
I tested it on another Windows 10 PC today and it opened the website. This is no restriction to the internet since the virtual machine worked, so i think it might be some windows security regulations restricting the functionality to open a website from a third party software?
So here is the dumb thing that happened.
I did not know that Mp3Tag was trying to open an authorization page using Window's default browser.
Yes, that is what Mp3Tag does the first time you try to tag with Discogs.
My default browser was Opera, and it was opened but crashed. I closed Opera with task manager and was able to complete the authorization. Discogs provided me with a 10-digit code.
To test if you have a similar problem, open a run dialog (windows button-r) then type http://
If your browser does not open, then Mp3Tag will also not be able to open it.
