Password not accepted ... Support?

Hello,
I have tried several times to install the ‘TrackingSpamPrevention’ plugin. The password must be entered during installation. I have entered this, but I always get the message that an error has occurred and that I should contact support:


Unfortunately, no specific support address is given for non-professional users … So I try my luck here - How do I get Matomo to accept my password? The password is of course correct (I have used it again in different browsers in incognito mode to log in to the Matomo user backend and it works there).
Thank you very much

Just try again. This error often occurs due to faulty session authentication and disappears on the second attempt.

Das habe ich schon 7 oder 8 mal …

Which browser are you using on which operating system?
Is an ad blocker activated?
Have you tried another user account?

Today the download finally worked :slight_smile:

(Previously tried several times a day with different browsers (latest versions of Vivaldi, Chrome, Firefox) under Ubuntu 20.04.6 LTS without success; no ad-blocker activated)
