Go lang client cannot obtain Let's Encrypt certificate

Help

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://mst.benhi.cn

I ran this command:

go lang client

It produced this output:

My hosting provider, if applicable, is:

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

no

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

no

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

go lang autocert

You'll have to post your full Go code if you want help with this. autocert works okay, the problem is going to be how you are applying it.
