Certificate not trusted

Help

i have just installed a next-cloud instance on my raspberry pi using their auto installer image. and following the links in

i have setup remote access using a free dNS server which is working and also enabled lets encrypt for a certificate which was issued fine with no errors

however my browsers are still reporting the site is not trusted

i have tried the following recommended tool
https://tools.letsdebug.net/
It produced this output:
cloudsaw.mooo.com is currently affected by Let's Encrypt-based rate limits (Rate Limits - Let's Encrypt). You may review certificates that have already been issued by visiting crt.sh | %mooo.com . Please note that it is not possible to ask for a rate limit to be manually cleared.

i have also used the

https://www.ssllabs.com/ssltest/

to check the site certificate and it comes back with a name mismatch error
any suggestions?

My domain is: cloudsaw.mooo.com

My web server is (include version):
nextcloud hub II version (23.0.2)

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

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): yes next cloud integrated web config tool

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

Please provide the commands you've run with the corresponding outputs. (The guide does not mention Let's Encrypt at all, so please provide us the necessary information yourself.)

It looks like you did get a certificate.

But it's not being used by your webserver. You have to install said certificate.

Thanks for pointing me in the right direction i had assumed it was a certificate issue.
The web based configuration tool only did half the job it did not set the correct paths to the new certificates
i eventually found the following set of instructions to complete the settings

https://docs.nextcloudpi.com/en/how-to-get-certificate-with-letsencrypt-using-dns-to-verify-domain/

with a couple of changes
in step 2 change python-certbot-apache to pyhton3-certbot-apache

in step 6 if the tab complete fails to work use the command
php -version and use the first two version numbers

thanks again for your help
