title: Pritunl server connection issues
body: <p>I created Pritunl Server successfully on my ubuntu 20.04 vps.
  Then when I try to connect to it using openvpn, I get a log message everytime...</p>
  <p>The log is:</p>
  <pre><code>Sun Nov 28 18:58:55 2021 Outgoing Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication
  Sun Nov 28 18:58:55 2021 Incoming Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication

  </code></pre>
  <p>But when I use a seperate proxy, It connects to vpn and works without any problems...
  What is the problem?</p>
