ERR_TOO_MANY_REDIRECTS after reset wordpress

I use Cloudflare flexible ssl on my website, all is going well. But When I reset the site, I can not go to my website admin. When type domainname/wp-admin, it returned “ERR_TOO_MANY_REDIRECTS”.

Then I go to Cloudflare.com to turn force https off, including page rules, Automatic HTTPS Rewrites, Disable Universal SSL, and finally Pause Cloudflare on Site. But I can still not be able to visit domainname/wp-admin. Who can help me to solve the problem? Thanks in advance.

If the rest of the site is fine, then check wp-config.php and set to the following

define('FORCE_SSL_ADMIN', true);  

Also consider changing from flex able to Full (strict)

More info on that at WordPress

Thanks for your advise, but in fact I have reset the wp, now it is a new installed wordpress site and all plugin disabled. After I pause Cloudflare and turn off force https on Cloudflare.com , all url should be without https. All should go to http. Why I can not go wp login page and it said ERR_TOO_MANY_REDIRECTS

Hi @howardhood, not sure what issue @hafid was having, I don’t see a contact to Cloudflare Support. WRT the ERR_TOO_MANY_REDIRECTS error, this tip is a good starting point, Community Tip - Fixing ERR TOO MANY REDIRECTS.
