title: `gpg: keyserver send failed: No keyserver available` when sending to hkp://pool.sks-keyservers.net
body: <p>I'm using the below command</p>
  <pre><code>gpg --keyserver hkp://pool.sks-keyservers.net --send-keys &lt;MY-8-DIGIT-SIGNATURE&gt;
  </code></pre>
  <p>as per guided by this article <a href="https://getstream.io/blog/publishing-libraries-to-mavencentral-2021/" rel="noreferrer">https://getstream.io/blog/publishing-libraries-to-mavencentral-2021/</a></p>
  <p>However, when I try it, it reports</p>
  <pre><code>gpg: sending key &lt;MY-16-DIGIT-SIGNATURE&gt; to hkp://pool.sks-keyservers.net
  gpg: keyserver send failed: No keyserver available
  gpg: keyserver send failed: No keyserver available
  </code></pre>
  <p>What's wrong with my command above?</p>
  <p><strong>Update findings</strong><br>
  This works on macOS Catalina, Intel Core i7 machine.
  But it doesn't work on macOS Big Sur, M1 ARM64 machine.</p>
  <p>Not sure if it is Big Sur or M1 ARM64 machine issue?</p>
