The problem happens rarely. I cannot reproduce it.

In the remote server panel, i right clicked one of the directories (www for a drupal 10 installation) and I wanted to know the size for the www-folder. Every time i clicket calculate (folder size) I got this message, I tried for another folder, it succeded. Then I tried the www.folder again, and this time it worked. So it might be a "first time" problem.
