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:

I ran this command: sudo certbot certonly --standalone -d optimate.wenbinzhao.com

It produced this output:

My hosting provider, if applicable, is: local

I can login to a root shell on my machine (yes or no, or I don't know): yes

Warning: Private ip address found. No connection possible. There are two types of ip addresses: Worldwide unique, global addresses and private addresses. If you want that other users connect your domain, your domain must have minimal one A- (ipv4) or AAAA- (ipv6) entry with a global ip address. Check Private network - Wikipedia to understand the details: 192.168.0.0 to 192.168.255.255: Class C - 256 private net, every with 256 addresses

A public visible ip address is required, not a private.
