My other website is hosted through DotNetNuke as a panel through IIS on my windows server however my node is on my ubuntu server. The domain mcresolution also runs a minecraft server at

My hosting provider, if applicable, is: I host myself at my house. I have 3 servers. One Windows Server 2008r2 Datacenter edition and 3 Ubuntu Server servers. One of those servers runs pufferpanel and the other two runs nodes for the main panel. Both nodes have no web interface but just use a daemon to connect to the main pufferpanel server. I have a resolving to the pufferpanel webserver (ubuntu server) on port 80 and I have resolving to port 443 on my windows server. All 3 of my servers share the same external IP address,

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Sort-of. DotNetNuke for a different website on a different server. All

you are using the TLS-SNI challenge

You are much better of using the DNS Challenge (add a txt record to your DNS) or HTTP challenge

–preferred-challenges PREF_CHALLS
A sorted, comma delimited list of the preferred
challenge to use during authorization with the most
preferred challenge listed first (Eg, “dns” or “tls-
sni-01,http,dns”). Not all plugins support all
challenges. See for
details. ACME Challenges are versioned, but if you
pick “http” rather than “http-01”, Certbot will select
the latest version automatically. (default: [])
