My domain is: conciliae.fr
My domain provider is: 1&1
I can login to a root shell on my machine (yes or no, or I don’t know): yes.
We have a website with a valid SSL Certificate delivered by Let’s Encrypt: conciliae.fr.
We send emails with an account activation link. When a Gmail user clicks on the activation link, Gmail displays a popup: “Suspicious link. This link leads to an untrusted site. Are you sure you want to proceed to conciliae.fr?”
We have looked for answers on several forums, but we have found nothing helpful.
Looks like the issue disappears after a while, like it was the case on this Let’s Encrypt Topic: Gmail displaying Suspicious link popup on links to site with Letsecrypt cert.
We also tried all the advices given on this forum: https://productforums.google.com/forum/#!topic/apps/xSV6J-Nmkmc.
On several forums we saw that it probably comes from the SSL Certificate we have, that’s why we publish the question here.
Because of this message we lose all our Gmail users (50% of all the inscriptions requests we have). This is a very problematic issue.
Would be great if someone could help us with this problem.
