[Desktop][Connect] Error code while logging in to my desktop app (error code 5)

[MarciK]

Hi community!

After turning on my PC today I found out that my app on Windows 10 was in "Offline mode" but my internet was okay and everything else ran smoothly. So I've decided to try to re-log into my account. I've logged out but when I've tried to Log in (I login via Facebook), nothing happens and after multiple clicks Spotify brings me to "A firewall may be blocking Spotify. Please update your firewall to allow Spotify. Additionally you could try changing the currently used proxy server (Error code: auth:5)".

I can connect to the Spotifys website and play music just fine from the same PC from Chrome browser.

I've tried reinstalling the app, changing proxy settings from "Default" to "No proxy", restarting my PC, but everything with no luck.

I also tried to search through this great community but I've had no luck finding any relevant topic posted previously.

Thank you in advance for any help!
