i,
* I had already reinstalled the app, cleared the app's data and deleted the app's folder in %LOCALAPPDATA%\Packages
* I have the issue on a desktop PC, which has a wired Ethernet connection; I have no other connection possibilities
* It does work on the same desktop PC within another Windows profile (so for another Windows user). It also works on my laptop, for both Windows users
* I had already opened up the firewall completely, so not a single thing would have been blocked
* Etc. etc.
Where the app works with an external auth provider (Google, Facebook or Apple) it goes like this: open the Windows app Spotify, select an external aiuth provider (e.g. Google), the default browser gets opened automatically, authentication occurs with the external (Google) account, I have to click on a button ("go to desktop app") in the browser and then the app appears, logged in successfully.
The one case where it doesn't work with an external auth provider (for 1 Windows user, only on my desktop PC): open the Windows app Spotify, select an external auth provider (e.g. Google), but nothing occurs then, except a few seconds later the app shows an error with technical error code: desktop_login_accounts:5 (does 5 refer to access denied, as is the case in many scenarios?).
AFAIK only Spotify has issues with external/Google accounts. Microsoft Edge is configured for every file type and protocol related to web (I've checked this: exactly the same config as for the profiles where there is no issue). Nonetheless I've tried to set Google chrome as default browser, but to no avail... It's like the app doesn't start the browser (by trying to go to a URL) or does try, but it fails because of an issue with the default browser, although outside Spotify every test has succeeded.
Is it possible to ask the dev team/product team when and why exactly the aforementioned error occurs? gain, it doesn't seem firewall or proxy related at all; I've found a case where the country was configured wrongly, but in my case this wasn't so. Also, I have found one case where the cause was no default browser was configured, but again, this doesn't seem to be the problem with me...

Pedro
