LetsEncrypt recreate or disable cert

Hello,

Show us a screenshot please.

Please give us the result of the following SQL query:

Replace <domain_name> by the domain_name.

I think that you'll have a result such as:

letsencrypt_status: Current error message as shown in your screenshot
letsencrypt_previous_status: torenew

So if yes, that means that there is a renewal problem. You can make a new renewal attempt through the debugger interface that is availables at: admin/imscp_debugger.php (admin level).

Note that on a renewal error there is currently no way to short-circuit the action. The only thing allowed is to make a new attempt as said above.

In your case, it seem that renewal fail due to an ACME validation problem. Such problem shouldn't occurs. So please, make a new renewal attempt and once done, post use the full content of the /var/log/letsencrypt/letsencrypt.log file (privately if you prefer).
