403 Error permission denied

Hi all,

recently added cloudflare to my site and everything seemed to be working fine until I tried logging back into admin I get the error

403 Permission Denied

If trying to access WordPress Admin please note that it is currently locked down by IP address for security reasons. Please contact support to have your IP address allowed access, this will take just a few minutes.
I have added the cloudflare plugin and changed ot to direct to https etc so not sure what is causing tyhe issue

Are there any suggestions for getting around this, I looked at other similar issues but nothing seems to fit with my issue

many thanks in advance
Sam
