 * Hi, I have this error trying to install the free license,
 * Recibimos un error al intentar activar la licencia con los servidores de Wordfence:
   Hubo un error al conectarse a los servidores de exploración de Wordfence: cURL
   error 7: Failed connect to noc1.wordfence.com:443; Connection refused
 * I already talk with the hosting, and they suggest to change the server. Is the
   server blacklisted by wordfence? This is the ip **45.55.50.99**
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcurl-error-7-30%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@srosales1000](https://wordpress.org/support/users/srosales1000/), thanks
   for reaching out to us.
 * The server IP hasn’t been blocklisted by Wordfence according to my searches, 
   but apparently _does_ appear on a single [UCE Protect](https://whatismyipaddress.com/blacklist-check)
   blocklist.
 * `cURL Error 7` often means that the website can’t make the connection to our 
   servers at all. This could mean that your host has a local DNS server that’s 
   caching a long-expired noc1 server IP, and is the most often seen reason why 
   this comes up.
 * If you have a shell on the server (or the host are willing to check for you),
   you could try running `curl -v https://noc1.wordfence.com/` and send us the output
   here. It’s not a perfect test since it’s not within PHP, but it may show if the
   server’s resolver is getting the wrong IP. Our IPs are available here: [https://www.wordfence.com/help/advanced/#servers-and-ip-range](https://www.wordfence.com/help/advanced/#servers-and-ip-range)
 * Let me know how you get on!
   Peter.
