How to check if renewed SSL is applied right or not

Website, Application, Performance Security

our domain uses cloudflare as the nameserver.
we applied an old ssl certificates on last October, 2022.
And we tried to applied the renewed ssl certificates on this October.

the ssl is not issued by the 3rd company, not this cloudflare.
when I check the webserver via PuTTy, it seems that the ssl certificate is applied well.
However, when I check the browser (chrome), the validation date of ssl certificate isn’t identical with the date of ssl I renewed.
I want to check the reason of the time difference between web-server and browser,
and then know how to fix this. Thank you…!

Is your domain proxied? And do you have Cloudflare’s Universal SSL feature active?

If your answer is YES to both questions above, then it’s the Cloudflare-provided certificate that is used for the link between the browser and Cloudflare, so that would be what you’re seeing in Chrome.

The certificate installed on your server is only used for the link between Cloudflare and your server.
