Hi @franksysgfx
I re-read this ticket and it seems my colleague slightly missed the point.
The error that you are getting doesn’t suggest allowing our IPs but it specifically says “If this is the case, whitelisting your server’s IP might resolve the issue.”
There is no implications for the site in terms of SEO/search engine indexing if you don’t allow our IPs. The troubleshooter feature works within your site and this error means that, basically, plugin on your site was not able to successfully connect to your site.
That usually still points to some sort of security configuration issues but may also be related to some server misconfiguration.
If you go to “Tools -> Site Health” page in your site’s back-end, do you see any warnings there related to SSL and/or loopback and/or cURL? If yes, what exactly these warnings are saying?
Also, despite troubleshooter error, are you able to actually visit and open sitemap URL of your site in browser – or are you getting some errors in browser too when you access it directly?
Kind regards,
Adam
