NEWBIE IP Confusion

Hmm… that wildcard record shouldn’t have anything to do with your blog, because it’s a directory and not a subdomain.

You can leave it there, but any subdomains not explicitly defined won’t get Cloudflare’s protection and it leaves your server’s IP address visible.

I’m not sure which errors you are getting, but you mentioned 504 and timeout, so here’s some info on those.

The 502/504 errors are caused by a problem connecting to an upstream server - meaning your server is trying to initiate a process and this fails to work as expected or times out. In most cases of 502 / 504 errors, back-end servers are not communicating correctly. When this happens, you will see color page with Cloudflare branding and the Error 502 Bad Gateway or Error 504 Gateway Timeout. Review this Community Tip for fixing 502 or 504 gateway errors.

A 524 error indicates that Cloudflare made a successful TCP connection to the origin web server, but the origin did not reply with an HTTP response before the connection timed out. Review the suggestions in this Community Tip for troubleshooting ideas.
