Hi @zone42, please check the following issue for a more detailed description and a workaround: [Logintoken are Invalidated 21.0.1 · Issue #26502 · nextcloud/server · GitHub](https://github.com/nextcloud/server/issues/26502).

The problem is that all auth tokens are renewed _at each login_ in version 21.0.1 which causes the slow login performance.

You can apply this fix from one of the comments as a workaround until it gets resolved in a release: [Logintoken are Invalidated 21.0.1 · Issue #26502 · nextcloud/server · GitHub](https://github.com/nextcloud/server/issues/26502#issuecomment-821983093).

Let me know if anything remains unclear!
