A curl(35) is not the typical response when your IP is blocked. This is more likely on your end.
Testing connections to codedesign.network results in a couple problems. One is that connections from various locations often take 30 seconds or more. I think it likely you also have issues on outbound connections.
More importantly, the cert returned is wrong. The cert being used names *.codedesign.app (not codedesign.network).
The only certs in the history for codedesign.network are wildcards (link here). Yet, the dehydrated request uses the http challenge. An http challenge does not support a wildcard cert. You must use DNS challenge instead for that.
As for the curl, do these succeed and how long do they take?
curl -i https://cloudflare.com
curl -i https://google.com
