To troubleshoot your site, you can pause Cloudflare globally. This will send traffic directly to your origin web server instead of Cloudflare’s reverse proxy. Paused domains do not use Cloudflare services such as SSL or WAF.
Within Overview, choose Advanced Actions > Pause Cloudflare on Site.
Alternatives to global pause
Instead of pausing Cloudflare globally, you can disable the proxy on individual records:
Go to DNS. Choose the record and select Edit.
Toggle Proxy Status off.
