@YounesGa To have each thread use only 1 line, set the value "max success usage: 1", "max number of simultaneous use: 1".
This is equivalent to the fact that after the flow finishes running with a result of Success, the already used proxy line will not be used again, whereas if there is an error, it will be reused 999999999 times and only one line. for each stream
