Qlik REST connector fails in Qlik cloud with error "Failed to connect to server The SSL connection could not be established, see inner exception."

[Andreas_Giesbrecht]

You might encounter the error "Failed to connect to server The SSL connection could not be established, see inner exception." when trying to connect to a REST API endpoint using  the Qlik REST connector in the Qlik Sense cloud services (but if you test the same connection on an on premise Qlik Sense version the connection might still work):

Please note that this kind of unexpected connection errors in the Qlik cloud might be caused due to incompatibility reason with the REST endpoint ciphers and the .NET 5.0 version in the Qlik Sense cloud. 

Accordingly we recommend to check what kind of ciphers are required for your endpoint and compare with default ciphers for .NET 5.0. In case of an incompatibility we suggest to upgrade the ciphers on the endpoint or to use the Qlik DataTransfer.

@Andreas_Giesbrecht  did you come right with this issue, I am experiencing the same. Using a rest connection to connect to an external website to get data, works  on prem qlik enterprise, fails hopelessly on Qlik SaaS, unfortunately we are not in control of the site that returns the json data.
