I have setup secret admin and password protection. I get a URL crawl error from Aimy
crawl-init: Failed to parse head: status code not found (255)
Both errors may have a couple of reasons, which are out of scope of Aimy Sitemap's crawler. The following enumeration introduces the most frequent reasons that we know of so far and how to solve them (if possible):
If you use Akeeba Admin Tools (PRO) on your website, be sure to allow both your website's public IP address and 127.0.0.1 ("localhost") to access your website without restrictions by adding them to the whitelist of the included web application firewall:
"Configure WAF" → "Exceptions from blocking" → "Never block these IPs"
However I think the administration security is causing the problem. Is there a way to allow and exception for the sitemap generation? I get the error.
