could not complete a loopback request
What is the issue you’re encountering
With Cloudflare proxy enabled we get a ‘could not complete a loopback request’ error in WordPress
What steps have you taken to resolve the issue?
Using Bot Fight Mode and WAF. Within Bot Fight Mode we have Definitely automated set to Block, Verified bots set to Allow, Optimize for WordPress enabled, JavaScript Detections enabled, and everything else disabled (Block AI Bots, AI Labyrinth and Static resource protection). SSL is set to Automatic and Full (strict) is applied. In WAF we have the default Cloudflare Managed Ruleset with no changes.
I’ve also tried setting up a Custom rule for source IP to the server’s IP set to skip rate, managed and super bot fight mode rules.
From what I’ve read in other posts this should eliminated the “could not complete a loopback request” error, but the error remains.
Was the site working with SSL prior to adding it to Cloudflare?
Yes
What is the current SSL/TLS setting?
Full (strict)
