Please help me solve the problem with the error.
When validating the site via [Nu Html Checker] gives an error message
IO Error : HTTP resource not retrievable. The HTTP status from the remote server was: 403.
Also I can not create a sitemap - the same error.
I contacted the hosting provider. They sent to Cloudflare.
Cloudflare, in turn, in the error description indicated that the problem is on the hosting side.
Such a football turns out - some send it to others, they return.
Please help me solve the problem with 403 error.
Thank you in advance
