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.

Hi @jeffenhuang, and welcome to the LE community forum
Please use the staging environment for all testing.
Once testing has been completed successfully, then you may switch back to the production LE system.

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
You are using "--standalone".
This implies there is no running web service.
But we can see something listening on HTTP port 80:
curl -Ii http://nmis-digf-sarif-a.nms.strath.ac.uk/
HTTP/1.1 404 Not Found
Date: Tue, 01 Aug 2023 17:35:41 GMT
Content-Type: text/html
Content-Length: 146
Connection: keep-alive
So, there is either some proxy/device in front of your web server OR we are not connecting to the right IP.
If there is a "proxy", it must be configured to proxy the ACME challenge requests to your server.
If that is NOT the correct IP, you need to update the DNS zone accordingly.
