SSL with DNS challenge fails due to propagation but ee thinks it renewed #1736
Description
Activity
A recent incident. Where one of my client changed dns to their sites. As ee renews all sites in a single command this broken ssl for all other sites. here is how:
- ee starts renewing one after another.
- if dns is changed at any moment. le just times out and thorws error. This exists the renew process. leaving all others sites below un-renewed.
- this keeps happening and eventually ssl for all sites below is expired and sites broken.
This needs to be fixed. Possible solution: Check DNS before renew.

Thanks for reporting this. It's fixed in EasyEngine v4.13.1 by site-command#505.
When a renewal doesn't produce a new certificate (for example because the DNS records haven't propagated yet),
ee site ssl-renew <site>now fails with an error saying the current certificate is kept, instead of reporting "SSL renewal completed.". The certificate files stay as they were, so the next renewal still sees the certificate as due and tries again.@prionkor, on the
--allcase in your comment:ee site ssl-renew --allnow continues past a site whose renewal fails. That site gets a warning and keeps its current certificate, and the remaining sites are still renewed.Please update with
ee cli update, and reopen this if you still see it.
Due to cloudflare we are using the DNS challenge method in order to renew the letsencrypt certificate of the site.
Even though the renewal has failed due to DNS records not being propagated, easyengine thinks that the SSL certificate has been renewed causing issues later on.
Issues such as not renewing the certificate when needed so the certificate expires. Not allowing to force renew so we have to delete the site and re-upload it.
All the issues cost money because of the time spend.
