403 disallowed_useragent error when logging into Spotify with Google OAuth

[buushh]

Is there a solution to the 403 disallowed_useragent error that occurs when trying to sign-in to Spotify using the Google sign-in option when I am in an application like Instagram or LinkedIn?

If users open a link within Instagram that links to my website that uses the Spotify OAuth, they are unable to sign in using the Google sign-in option since my app opens up within Instagram and not in a separate browser window.

Anyone else experience this issue?

I have attached a screenshot that shows the error while in Instagram:

same issue for me. I was trying to access the Spotify App on the Garmin Forerunner 245 Music, but it gives me error 403 in authentication when try to log in from the Connect App.
Here is the message:
