additional warning before the error:

WARN [AspNet.Security.OAuth.Discord.DiscordAuthenticationHandler] [CorrelationCookieNotFound] '.AspNetCore.Correlation.5UOMY7CEJtfm8pa<snip>' cookie not found.

i'm able to login successfully. is there anything in the browser console that might indicate the error? does this consistently happen always? or did it start recently?

got a related issue, but i may have a hint, the callback_url is http and redirected to https.

yeah, this keeps popping up every once in a while and it seems like just trying again works? super inconsistent. would need to know browser and OS to see if there's a pattern

I get this 100% of the time on my phone using either Samsung Internet browser or Google Chrome browser. And 100% of the time on my windows 10 computer with Chrome or Edge. Have never been able to login.

After reading the code on line 195 in Startup.cs an guess is that the because I have never chosen an avatar on Discord. This might result in line 198 user.GetString("avatar")!.StartsWith("a_") to crash with a System.NullReferenceException: Object reference not set to an instance of an object. exeption. Note the "!" after GetString.

After uploading an avatar on Discord I can now login so it seems related to that.
