When consuming a web service over HTTPS, the server hosting the web service may be using a self signed certificate (for example, for non productive web services).
To successfully establish the trust relationship, the self signed certificate used on the web server must be added to the trusted root store of the servers that host the Platform Server.
In these situations, when this step isn't done, errors like
Could not establish trust relationship for the SSL/TLS may occur.
OutSystems servers must have a valid SSL certificate issued by a public Certificate Authority, as described in OutSystems system requirements.
For OutSystems Cloud environments check this article instead.
