Where are you hosting the page? That error means Cloudflare can’t access it. It may be being blocked by the a firewall rule you configured so you should check the events log for any entries and, if there aren’t any, see if your server may be blocking the request.
Thanks for taking the time to help! I’ve reviewed the WAF logs and cannot see any blocks to the page to be sure, I setup a WAF rule allowing all to the page URL so I could track Cloudflare visiting the page.
That is odd, I have tested it on my account and am able to successfully get it to take the page. As it is clearly being allowed through the Cloudflare WAF and you can see from the server logs that your server is returning the page I’d suggest opening a support ticket, if you haven’t already, to see if they can track down where this is failing.
Shortly after your reply we worked out what the issue was just reporting back for future people who will Google this.
There seems to have been a change made to the way Cloudflare grabs the pages via custom pages. For some reason if we remove the meta tag base href, Cloudflare will grab the page and not report a 1202 but if included in the page it will error out.
We have older custom pages that have the meta tag base href so it was acceptable in the past but now you cant submit any custom pages with it. (at least we can’t)
