Hello everyone,
On my GoDaddy/WordPress site using Cloudflare, Chromium browsers experience a 503 error on subsequent visits after passing the initial challenge and obtaining a persistent cf_clearance cookie (which is sent with the request, unlike Firefox which works fine), and diagnostic testing showed that spoofing the Chromium User-Agent to Firefox while the cookie was present resolved the 503 error, indicating a User-Agent-based block occurring after the initial Cloudflare clearance. How to resolve this issue? Who to contact? Can anyone help? Thank u.
