Hello All, I’m getting below error while invoking rest API using Call REST Post activity in microflow. This error is happening very random and there is no clear steps or path to reproduce the issue.

The actual error is: java.security.PrivilegedActionException: javax.net.ssl.SSLException: Connection reset

Try to google this error. There are lot of reasons why this could happen. Try to strike out every reason until you find the solution for this. 

https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLException.html

https://www.csoonline.com/article/3246212/what-is-ssl-tls-and-how-this-encryption-protocol-works.html

In short, you are making a REST call to a https URL, which has some issues getting connected.

What I recently encountered is, companies started using the latest TLS version. So, I got some errors when this does not match. May be its good to check that as well.

Hi,

In your microflow, make sure to close the connection at the end.
