Hello,
I am using a Windows server 2019 with IIS and active websites, for some reason when i enter a website that exits in our IIS with HTTPS with valid R3 certificate from our server it loads an expired certificate ( i have tried Chrome Edge and Mozilla to test this). I entered me certificate manager using MMC and i cant find this certificate anywhere on the server, i reinstalled all the browsers i even removed the new certificate that was granted to the website and created a new one but still the same error. This problem occurs only in the server and not on any other computer. What could be the problem?
Thank you in advance

2023-01-24T06:44:27.42+00:00 Already checked the certificate that is selected in IIS is the updated (to be more specific it's the only certificate available because the old one is removed) , just to refresh this problem happens only on the server and not on other computers.

The browser may obtain the page from the cache or from an existing open TLS session with the server, which means they'll never see the new certificate, which is only received in the TLS handshake stage. Close all browser windows to kill the existing sessions (and optionally restart your computer), then check if the problem persists.
Hope this resolves your Query !!

2023-01-27T07:11:02.96+00:00 I found the problem, i have two servers (one production and and the second is a hot standby) when i entered the website the request went to the standby server where the certificate was old (only renewed in case of a crash) and not the to the server itself, i just shutdown the iis service at the standby.
