SSL error. Its security certificate expired yesterday. What to do?

Question

Browsers

I wanted to enter the site of my VPS hosting, and then some oddities began, first some kind of security warning appeared, I ignored it, then a form appeared like the same site, asking me to enter a login password, although it was always remembered by my browser, and here I thought. And suddenly it's some kind of hack. Once again I decided to enter the site.
The following appeared:
Your connection is not private
Failed to verify that this is a server (hosting_domain). His security certificate expired yesterday. Perhaps the server is configured incorrectly, or someone is trying to intercept your data. Note that the time on the computer is set to Saturday, July 7, 2018. If it's incorrect, change it and refresh the page.
You cannot continue because the site operator has requested increased security for this domain.
I don’t really believe in hacking, and who needs it, and how, but still, is there at least some chance that someone doesn’t have something to do?
(I have a router, the computer is connected via a cable to the router, a large LAN like everyone else, a gray IP almost like everyone else)

Answer 1

Yes, just someone forgot to renew the certificate.
Give a link to the site, we'll see.
