I have a similar issue. After changing to Cloudflare, my site responded with “Error 525 Handshake Failed”
At this point, I cannot access files, the account is at GoDaddy. It’s a “Basic Managed Wordpress” hosted account, I was able to get to the files yesterday via ftp, but not anymore. It’s not like my other URL, ( also through Cloudflare and works fine) which has Cpanel access to the files. This account does not.
It’s been about 15 hours and still no change in the response. I’ve tried Firefox, Chrome, IE 11 & Opera with no success. The URL that’s not accessable is partsforu.com. The other site that’s ok, it tommillersmotorsports.com. I even removed Cloudflare for a bit ( probably not long enough) and nothing changed. Site24X7 reveals the Cloudflare DNS and the all 6 servers refused query. UpTime Robot shows 100% up time. Whatever the reason I’m having such a problem with this one I have no cuse. . but I am suspecting it’s something I’ve overlooked. As stated, my other site works. . not this one. Appreciate any help you can offer. Thanks In Advance, ~T²
