I have exactly same on version 31.0.5.
I’m using keepass files via WebDAV and all my keepass apps (Windows, Mac, IOS, Android) cause HMAC Exception. Table oc_storages_credentials in MariaDB is empty.

Hi all!
I have the same error message on a clean install. No add-ons, or anything. I’m going to file under “bug” until further notice.

The GitHub issue [Bug]: HMAC does not match. Could not decrypt or decode encrypted session data · Issue #42157 · nextcloud/server · GitHub is still open. A pull request is currently marked as “Draft,” fix(session): Make session encryption more robust by ChristophWurst · Pull Request #47396 · nextcloud/server · GitHub which may eventually resolve the problem. Until that PR is officially implemented and merged, it’s best not to assume the issue will be fixed in upcoming server releases. Keep an eye on the repository for updates.
