Hey @farida,
Very strange! I just checked our server logs for 403 responses sent for your domain and do not see any, so I’m not sure where that’s coming from. I thought maybe your DNS might be misconfigured and that another service was serving a 403, but your DNS looks good to me and we have created an SSL certificate. So I’m a bit stumped! Could you please share a screenshot of the error you see and an x-nf-request-id?
