AutoSSL keeps expiring then won't install new cert

[emar]

Can anyone explain how to get autossl to install.
I went to ssl certificates and see the autosll cert has expired again,
So I deleted the cert then clicked AutoSSL FREE and tried to create a new cert.

I've no clue why I have to keep renewing this cert, can I set it to auto renew?

How do I fix this issue, can't instal la new cert.

Error...!
DNS of your domain doesn't point to this server or you have htaccess restrictions

I have a .htaccess in the public_html

I just clicked Force All Renovations under SSL certificates then it renewed the cert.
How do I make this cert auto renew before it expires each time?

Select the 'Activate' tick box under Apache Settings > SSL Certificates > Configure tab & click save

It's already ticked, under Auto Renovation
