 * Hey there guys!
 * Test e-mail gives me Request Timeout 500 internal server error. The same with
   woocommerce when doing checkout.
 * It was working few days ago. Tried disabling Lite speed cache plugin. Did not
   help.
 * Could this be related to Cloudflare? It is the only thing that comes to mind 
   that has changed in past days.
 * I am using your plugin on the same hosting on other website and it is working.(
   that website is not connected to cloudflare)
 * Thank you and looking forward to your answer!

 * Just tried to configure WP Mail SMTP plugin on another website which uses Cloudflare.
   It does not give internal error, but no matter what settings I set it gives me:
   There was a problem while sending the test email. Could not authenticate your
   SMTP account.
 * I know that settings are correct, because I use them on a site where it works.(
   without cloudflare)
 * P.S. I dont know why but the other site with Cloudflare also just started to 
   load for long time and give me this error after pressing test email

 * Solved it!
 * Just change in Cloudflare DNS Settings proxy status for email from Proxied to
   DNS only and problem is gone in a second.

 * Maybe this can hel someone else too. 3 hours wasted :)))
