ERRRO? Failed to renew certificate with error: Could not bind TCP port 80 because it is already in use by another process on this system (such as a web server). Please stop the program in question and then try again.
I moved your post to its own thread. We like each to have its own. Had you posted in Help section first you would have been shown the form below. Please answer as much as you can so we can help you.
But, just based on the error I'd guess you previously used a standalone method that requires exclusive use of port 80. And, that now you have a webserver running and using that port so they conflict.
The answers to the below will help us give further advice if you need it.
=================================
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

My domain is:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
