We have changed something with certificates and how we can retrieve it. Previously we faced an issue that was we could request a certificate but we were not aware about if the certificate was accepted by the acme challenge or not, now it is
When you issue to request a certificate you can be aware about it, I tried to resume my mind with a pull request
and something if you want to test the new behavior
lets_encrypt True → you ask a certificate, we wait until it is accepted, we fail if not and we display a failure state, now in a banner with my new code
lets_encrypt False → you set the relevant certificate obsolete and you restart traefik, http web access through traefik could be interrupted
lets_encrypt not sent , this is what the code does, do nothing
Since we stop to configure now when the certificat is not good, we should do not configure lets_encrypt on clone and restore action, hence we have removed it
Now you have a button in the tooltip to reach the certificate page
When Lets_encrypt is set, requested, issued with a valid certificate, you have a banner when you try to set the toggle False, explaining the certificate will be obsoleted and traefik will be restarted.
