cURL error 28: Connection timed out after 10000 milliseconds. I have verified that my PHP INI settings are as you suggested in other threads: memory limit(256M) and maximum execution time(300). I am also using php 7.1. My hosting provider has verified that cURL is configured properly as well. We test to make sure the firewall was not an issue and it was not. We took it down, tried validating and still no success. The domain routes through cloudflare. I enabled development mode and that still did not help.
This is extremely frustrating.
