Hi Andrew,
It sounds like you're running into an issue with Moz being unable to access your robots.txt file, even though other crawlers and your browser can access it. Since your site is on SquareSpace and DNS is managed through Cloudflare, there could be a couple of things to consider:
Cloudflare Settings: Sometimes, Cloudflare's security settings (like firewall rules or bot management) can block certain bots, including Moz's crawler. You might want to check your Cloudflare settings to ensure that Moz’s IP addresses or user agents aren’t being inadvertently blocked.
Robots.txt Caching: Cloudflare may cache your robots.txt file. Try purging the cache for that file specifically to ensure the most up-to-date version is being served. This can sometimes resolve issues where different services see different versions of the file.
SquareSpace Configuration: Double-check if SquareSpace has any additional settings or restrictions that might affect how external crawlers, like Moz, interact with your site. Since SquareSpace handles a lot of things on the backend, their support might be able to provide more insight.
Allow Moz in robots.txt: If Moz’s specific user agent isn't listed in your robots.txt file, you could try explicitly allowing it by adding the following to the top of your file:
User-agent: rogerbot
Allow: /
If the issue persists after checking these, reaching out to Moz support with specifics about your setup might help you get more targeted assistance.
