<p>I'm seeing very frequent &quot;no healthy upstream&quot; error on one service calling the other. Due to confidentiality of project cannot share much details.</p>
<p>kubectl pod logs shows something like below:</p>
<pre><code>pod1 - restart(1)
pod2 - restart(0) -&gt; throws no healthy upstream error.
</code></pre>
<p>looks like pod2 trying to connect to pod1 but get the error.</p>
<p>Also, could it be an issue with virtualservice / destination rule.</p>
<p>A newbie here</p>

<p>In <a href="https://github.com/istio/istio/issues/29254" rel="nofollow noreferrer">this</a> GitHub issue on the Istio project, you can try and go through the checklist in the issue description to verify that the service components are functional.</p>
<p>There is also a good discussion in the comments section that can help you solve the problem. Something simpler like restarting the ingress gateway has also been known to work.</p>
