<p>After upgrading the jenkins plugin Kubernetes Client to version 1.30.3 (also for 1.31.1) I get the following exceptions in the logs of jenkins when I start a build:</p>
<pre><code>Timer task org.csanchez.jenkins.plugins.kubernetes.KubernetesClientProvider$UpdateConnectionCount@2c16d367 failed

<p>After some of these eceptions the build itself is cancelled with this error:</p>

<p>Do you have an idea what can be done?</p>

<p>Downgrade the plugin to kubernetes-client-api:5.10.1-171.vaa0774fb8c20. The latest one has the compatibility issue as of now.</p>
<p><strong>new info</strong>: The issue is now solved with upgrading the <strong>Kubernetes plugin</strong> to version: 1.31.2 <a href="https://issues.jenkins.io/browse/JENKINS-67483" rel="noreferrer">https://issues.jenkins.io/browse/JENKINS-67483</a></p>
