Request has been aborted: Could not create secure channel for SSL/TLS

Hello,

I have an integration with Jira that was working until recently and has now stopped working.

When running the application, the message is displayed:

Request has been aborted: Could not create secure channel for SSL / TLS

I am using the .Net Framework 4.5.2, and when changing to a higher, for example, 4.6.1, the error no longer occurs, however the projects I look for in Jira are not returned.

See below:
