Uploading multiple files in the panel : The imagemagick convert command could not be executed: 'convert' -limit thread '2’

Alright, seems like OVH is blocking the multiple threads.

'thumbs' => [
        'driver' => 'im',
        'threads' => 2, //remove that line
        'bin' => 'convert',

Everything is working fine now.
