 * All was well until now, when I found the website is not being cached at all.
 * I have looked around quite a lot without finding anything and also asked my web
   hosting for help. They are saying:
 * “If you’re trying to make a CURL request from your website, we’re likely blocking
   it.
    This would be considered as a loopback connection, where the website attempts
   to make an external HTTP request to itself. We’d block this unfortunately.
 * I would recommend you to contact the plugin Author and ask them if there is a
   way to use this plugin without loopbacks (without HTTP request). ”
 * Having uninstalled W3TC altogether and reinstalled from scratch I still have 
   the same error: cURL error 56
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcurl-error-56-4%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Sounds like you are using the precache loader, whereby you are having w3tc recache
   pages after a certain time. Seems like a dik move by your provider blocking loopback
   http requests. You could use a proxy to get around this problem.

 * What do you mean by precache loader? I’m only using the free version here and
   there aren’t any options I can see on precaching.
    My hosts are Heartinternet
   and they just won’t budge on CURL requests.

 * Hello [@manog](https://wordpress.org/support/users/manog/),
    I think that [@fistfullofcrisco](https://wordpress.org/support/users/fistfullofcrisco/)
   meant “Cache Preload” in Performance>Page cache, Cache Preload sub-box
