I created a site that I want to have on a custom domain. The site https://full-p.webflow.io is working and I added all DNS records to my admin provider. However, when I go to https://fullp.cz where I want my website to be located, it gets redirected to https://www.fullp.cz and then shows the 403 error.
I contacted my domain and hosting provider and they said everything is OK on their end. Also, the Webflow check system says everything is correct.
Thank you very much for your help.
