Hi,
When I try to submit my sitemap to the Google search console it returns the error
“Your Sitemap does not contain any URLs. Please validate and resubmit your Sitemap.”
I can view the sitemap fine on my website.

I tried to validate in some other validators and the also returned errors even though it shows fine on my site. My host is using varnish as the cache, do I need to exclude some urls from the varnish cache or similar?

Thanks
Nik
