I have a multi-site hosting solution for 2 websites, and starting yesterday, it looks like I receive the infamous NET::ERR_CERT_COMMON_NAME_INVALID message for both of them.
This server could not prove that it is digitalhealthcentral.com; its security certificate is from hosting.cdn.ovh.net. This may be caused by a misconfiguration or an attacker intercepting your connection.
I tried to regenerate the SSL certificate, but so far, nothing works…
Have to say this is really frustrating,
Any help from tech-savvy people will be more than welcome.
