SYMFONY 4.3 HttpClient Hostname was NOT found in DNS cache

I am using the Symfony HttpClient Component to connect to an EXTERNAL API but it throws me the following error:

  • Hostname was NOT found in DNS cache
  • Added services.informa.es:0:185.20.117.137 to DNS cache

Anyone have any ideas?

I am using Symfony 4.3
