For starters, welcome, but please note that this is an English language forum. So please write your messages in English. We’ve seen more reports about issues like this, but we haven’t quite figured out the root cause yet. Could you try to add it with a different browser please? As far as we know, this is caused by some browsers/browser configuration or browser extensions.
