Possible workarounds

• Redirect all 8443 requests to a single URL

  On Linux, configure a redirection so that all https://<domain_name>:8443 requests will be redirected to https://<hostname>:8443. To find out how, refer to this KB article.

• Use Cloudflare to block access over 8443 for a domain

  If domains are behind Cloudflare, it is possible to block all ports except 80 and 443 on the Cloudflare side. To learn more, visit this guide.
