REST connection Failed to connect to server The SSL

fomichevam — Fri, 23 Apr 2021 12:19:46 GMT

Hello
I use qlikcloud (SaaS Qlik Sense)
When using a REST connection to receive data via https, I get an error:
Failed to connect to server The SSL connection could not be established, see inner exception.

Parameter
Certificate validation = Skip Server Certificate Validation

From Postman everything works fine

What do you need to check?

Hello @fomichevam

Have you enabled TLS 1.1 or 1.2 in registry? If no please refer to below link:

@PadmaPriya Your solution appears to target Qlik Enterprise (locally installed) the OP (as am I) is using Qlik SaaS (Cloud)?
