Call web Service - Failed to invoke web service

We have workflow running on a document library in SP 2013.

 

Most of the time workflow executes fine. However, once in a while we get an error in one particular action which calls the web service.

The error is:

Failed to invoke web service. Error returned from server: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

 

The action is configure as shown below:

The only strange part is the error is completely random. It does not happend for any specific user or scenario.

Hi imran,

 

any chance you can check sharepoints ULS logs at the time the error occurs? Could be some infrastructure issue.
