Today, suddenly we receive this message when trying to open links to our webpage though our newsletter, from different computers, different locations.
The cause comes by “Invalid name of certificate” which comes from from a big and reputable newsletter campaigns website (sendinblue.com) and specifically their redirect domain (r.mailin.fr)
We check our domains (www.lefkada-rentals.com) on opentip.kaspersky.com and they look safe. The same occurs with sendinblue.com and mailin.fr)
What can we do? Of course we dont want just to skip the check from local computers, as this block will occur to many of our guests who receive our newsletter.
Thank you for your help!
