Hello, I have been trying to set up my letsencrypt docker following this guide. https://cyanlabs.net/tutorials/the-complete-unraid-reverse-proxy-duck-dns-dynamic-dns-and-letsencrypt-guide/ I get the following error from the docker when I run it. Failed authorization procedure. DOMAIN.duckdns.org (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Error getting validation dataIMPORTANT NOTES:- The following errors were reported by the server:Domain: DOMAIN.duckdns.orgType: connectionDetail: Error getting validation data I have also tried a noip dynamic DNS but I received the same error. I also disabled my firewall to check to see if that was the problem but I received the same error. Ideally what I want to do is use the domain I bought in this, but I bought my domain through squarespace and have no idea how to do that. Any advice in this situation would be appreciated.
