<p>I have local kubernetes cluster on vm.
I use containerd as a CRI.
and when i install calico, have the next error with calico-kube-controllers</p>
<blockquote>

</blockquote>
<p>P.S with docker as a CRI, works fine</p>
<p>OS version Red Hat Enterprise Linux Server release 7.7 (Maipo)</p>
<p>Openssl version OpenSSL 1.1.1  11 Sep 2018</p>
<p>Configuring tls-min-version for kubelet and kube-api-server didn't help.</p>

<p>solve the promlem.
my cluster works behind corp proxy, and containerd sent requests to 10.96.0.1 through the proxy.
i just add IP 10.96.0.1 to non proxy list to containerd proxy conf.</p>
