WEB API Error

Question

Hi,

I have a project made with .NET Core 3.1. There has been a slowdown in this project lately. The project is querying with WEB and WEB API. Sometimes I get errors like this. What is the solution to this?

SocketException

IOException: Unable to read data from the transport connection:

HttpRequestException: The SSL connection could not be established, see inner exception.

Hi,

But when I look at the server and enter the site, the SSL certificate appears. Also, for example, I get this error, it works when I refresh the page. In this case, what could be the problem?
Here is the output of the error.
