I have read this issue somewhere before and seems to be related to CloudFlare RailGun.
My site worked well as usual with RailGun which is always turned off.
Recently there's this redirection loop with message "Please wait while your request is being verified"
If I turn on RailGun and set CloudFlare to Developer Mode, the issue is only shown once and it works.
But this is not how it usually works as I don't use RailGun and it is an issue that I have read if this is turned on.
