[ShadowOfHeaven-Me]

What happened?

No forceLogin and forceRegister occurs in 1.21 Also, this error happens on reloads and proper disables:

Steps to reproduce

Use Paper 1.21, fastlogin and use my auth plugin Alix.zip

Is how the debug message looks like. (It was tested on localhost, that's why the loopback address)

I should also mention that spark detects the invocation of forceLogin, however, during my testing, it was never invoked

Btw, you should also have autoRegister be true by default

[TuxCoding]

FastLogin skipped it's own authentication, because the auth plugin already logged the player in:

joined and was automatically verified for: IP AutoLogin

[ShadowOfHeaven-Me]

The thing is that forceLogin and forceRegister are never invoked, and any premium checks return false. Also (on 1.20, when force login did work), why does BukkitFastLoginPreLoginEvent#getProfile#isPremium return false sometimes, but invokes forceLogin or forceRegister later on, when the player is premium?

FastLogin skipped it's own authentication, because the auth plugin already logged the player in:

joined and was automatically verified for: IP AutoLogin

Forcelogin never happens, even if the auth plugin doesn't automatically log in the player

[ShadowOfHeaven-Me]

ping me when you find the issue

[ShadowOfHeaven-Me]

Are you having trouble reproducing the error? Or is it caused by ProtocolLib?

[ShadowOfHeaven-Me]

Um

The same error on server shutdown with paper-1.21.1-57. I use it together with UserLogin plugin.

It's really weird how delayForceLogin is invoked, while the actual forceLogin method isn't

[RobertGaminPlayz]

idk if my issue is the same but it may be similar. There are no errors on bungee but the errors from lobby shows this... Basically the issue is it doesn't force register the player.... It uses the latest FastLogin and Authme plugin on the servers bungee or paper.

(It was fixed in the latest build)
