HTTPS certificate quality problem?

And what answered Paypal on your question?
I think first question you send on Paypal, isn't it?

[webmasto]

The certificate is active

[Jumbo!]

You need to upgrade your SSL certificate. It must support TLS 1.3. See - https://www.cdn77.com/tls-test?domain=www.staysafemanipulite.com

[webmasto]

I created a second folder on the main server to be able to test the program.It is: https://www.staysafemanipulite.com/vetrina/index.php/cart

[webmasto]

The TLS 1.2 protocol is installed on my server

[Jörgen]

As jumbo Said, you need tls 1.3

No expert on this dull subject but my server with many VM sites using paypal hasn't got 1.3.. 

Is it certain that it is a requirement?

[Jörgen]

I guess You are right GJC,
https://developer.paypal.com/docs/api/info-security-guidelines/

Tls 1.2 or higher. Back to square one.
