WHM updated last night apparently with a problematic version of libcurl. The symptom is that PHP initiated libcurl SSL connections fail with the following error: OpenSSL SSL_read: Success No data is returned from the call. This completely breaks outbound API and webservice calls for some services. This appears to due to this bug:

  Hello, Yes this is something we're aware of and the only solution right now is to downgrade curl with: yum -y downgrade ea-libcurl-7.66.0-1.1.2.cpanel
  then add ea-libcurl
  to exclude in /etc/yum.conf
  until the updated package is pushed out. This should be done early next week.

  Is this still an issue or is a patched version now available for EasyApache updates?

  I believe this was fixed because I tested one server on which I faced an issue. I installed all updates OS/cPanel and I am not facing this issue anymore. - Kailahs

  Yeah, I later found this article stating that ea-libcurl-7.67.0-2.2.1.cpanel.x86_64 fixes the issue that was broken with ea-libcurl-7.66.0-1.1.2.cpanel.x86_64
