title: Go Module Not Downloading Latest Minor Version
body: <p>I am using <code>go version 1.13.1</code>, and now I cannot update my dependecy module to the latest minor version using <code>go mod</code>, I made simple repo for learning dependency management on <code>github.com/clavinjune/testng</code> and made a project that depends on it called <code>moduser</code>.</p>
  
  <p>The latest minor version of <code>testng</code> is <code>v1.4.0</code></p>
  
  <pre><code>┌─[ ~/Public/testng ]─[ git:master ]
  └─[ 22:09:19 ] $ git tag -l
  v1.0.0
  v1.1.0
  v1.2.0
  v1.3.0
  v1.4.0
  </code></pre>
  
  <p>and <code>moduser</code> still using <code>v1.3.0</code></p>
  
  <pre><code>┌─[ ~/Public/moduser ]
  └─[ 22:09:06 ] $ go list -m all
  moduser
  github.com/clavinjune/testng v1.3.0
  </code></pre>
  
  <p>when I want to update the dependency I run this command</p>
  
  <pre><code>┌─[ ~/Public/moduser ]
  └─[ 22:20:17 ] $ go get -v -u github.com/clavinjune/testng
  ┌─[ ~/Public/moduser ]
  └─[ 22:20:28 ] $ go get -v -u github.com/clavinjune/testng@latest
  </code></pre>
  
  <p>But it doesn't downloading the <code>v1.4.0</code>.</p>
  
  <p>Is there any wrong command that I run ?</p>
