title: Webscraping, read_html() - Error in open.connection(x, "rb") : SSL certificate problem: certificate has expired
body: <p>I am currently trying to build a small webscraper.</p>
  
  <p>I am using the following code to scrape a website:</p>
  
  <pre><code>webpage &lt;- "https://www.whisky.de/shop/Schottland/Single-Malt/Macallan-Triple-Cask-15-Jahre.html"
  content &lt;- read_html(webpage)
  </code></pre>
  
  <p>However, when I run the second line with the read_html command, I get the following error message:</p>
  
  <p>Error in open.connection(x, "rb") : 
    SSL certificate problem: certificate has expired</p>
  
  <p>Does anyone of you know where this is coming from? When I used it a few days ago, I did not have any trouble with it.</p>
  
  <p>I am using Mac OS X 10.15.5, RStudio (1.2.5033)
  I also installed the library "rvest"</p>
  
  <p>Many thanks for your help in advance!</p>
