Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:https://myrichnas1.myqnapcloud.com
I ran this command:没有用

It produced this output:

My web server is (include version):https://myrichnas1.myqnapcloud.com

The operating system my web server runs on is (include version):QTS 5.2.6.3195

My hosting provider, if applicable, is:qnap

I can login to a root shell on my machine (yes or no, or I don't know):不知道
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):apache

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):不确定

from my perspective both port 80 and 443 looks closed, as expected because in China you need ICP filling from Goverment: which is unlikely in your case as it's nas ddns

Use your own domain and use acme.sh
