If you encounter a problem of reliability or validity of a certificate when you try to connect to your account, especially the first time, also on iPhone since January 2017 (iOS 10.2 or higher), but also on your messaging application when you try to connect using the recommended secure settings; you are certainly facing a problem of validity or generation of the SSL certificate associated with your domain.
When creating your account and associating any new domain name, our "AutoSSL" module will automatically generate and renew your SSL certificates. It tries several methods (DNS/HTTP) until it succeeds in validating it, of course insofar as your domain name does indeed point to one of our servers.
SSL certificates allow you to secure your accesses, not only e-mail but also web/https and SFTP. More details: What is an SSL certificate and what is it used for?
In some specific cases, especially when transferring existing domains after the creation & configuration of your account, it may be necessary to force the generation of a new certificate manually. Here is how to proceed:
Step 1: Login
You must first log in to your Control Panel. If you don't remember how to do this, here's how to do it: How do I log in to my account?
Step 2: Generate your SSL certificate
Warning: If your certificates were previously generated directly using Let's Encrypt SSL (old method, still available on our servers), you must first delete your certificates generated by Let's Encrypt SSL before asking AutoSSL to do it. We recommend that you perform this operation during low traffic hours as your site may be without a valid certificate for up to 20 minutes.
- In the"SECURITY" tab, click on"SSL/TLS Status" :
- In the"SSL/TLS Status" interface, click on"Run AutoSSL":
: It may take up to 20 minutes for the new certificate to be issued. After this time has elapsed, return to the AutoSSL interface to verify that the certificates were generated correctly.
