<p>Hi Ionut,</p>
<p>I didn't see this before on our production. Magnum auto healer
just simply sends a POST request to Magnum api to update the
health status. So I would suggest write a small script or even use
curl to see if you can reproduce this firstly. <br>

<div>Currently, I only have 4 clusters.</div>
