Hi all

Since yesterday me and my users all around the world faced with the error message on the login screen which appears right after the page is loaded, before any login attempts:
We have detected multiple invalid login attempts from your IP. Therefore your next login is throttled up to 30 seconds.

I do not have BruteForce application.

I can log in to the system.

Also, some of my users experiencing troubles while sharing content:

Is this the first time you’ve seen this error? : YES

The output of your Nextcloud log in Admin > Logging:
I have the usual OCP\Files\NotFoundException error, and also something new:

Any suggestions?

Had the same problem on a brand new install. I truncated the table oc_bruteforce_attempts and could log in. I think my desktop client may have been trying to log in between install and my recreating a new account for me. Shrug.
