Security Protocol

Hello everyone, hello @Ruri, i have a technical question for you.
I have a strange issue with my config.
With security protocol “systemDefault” i get a wrong response.
I change to “TLS 1.0” and my config is ok for a short time.
When i get a wrong response again, I change again to “TLS 1.1” and my config is working again but for a short time only.
But after changing these 2 times, the config no longer runs and always returns wrong answer.
How can I solve this situation and above all I would like to understand what it depends on.
Thank’s in advance.
