PostMan: HTTPS Get request/ The underlying connection was closed: could not establish trust relationship for the SSL/TLS secure channel

Question

I am making HTTPS get request through PostMan I am getting the following error message : The underlying connection was closed: could not establish trust relationship for the SSL/TLS secure channel. is there any specific setting should I do it in PostMan (like adding on the request ) ?

BTW: the Url I am calling is based on Mulesoft

As it is get request, did you tried on chrome or explorer, so you would understand if it is a SSL certificate issue with postman — Ven

You can try the following; however, it's not recommended:

Postman >> Preferences >> SSL certificate verification OFF
