title: ERR_SSL_VERSION_INTERFERENCE on Chrome
body: <p>I have a website that uses <a href="https://github.com/sta/websocket-sharp" rel="noreferrer">websocket-sharp</a> for client-server communication and has a certificate issued by <em>Let's Encrypt</em>. Other browsers work, but Google Chrome (on Linux) gives the error <code>ERR_SSL_VERSION_INTERFERENCE</code> in the console. Disabling TLS 1.3 lets users circumvent this error. I am using the latest stable version.</p>
  
  <p><a href="https://superuser.com/a/1217757">This</a> answer suggests the problem is when Chrome detects <em>"buggy middleware"</em> but I don't know what exactly Chrome is looking for.</p>
