Problem connecting to HTTPS web data via basic auth

[mscherotter]

In Power BI Desktop, I am trying to get web data via an HTTPS REST API using basic authentication. I enter the username/password in the data source settings but I consistently get this error message:

    We encountered an error while trying to connect.

    Details: "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

I've tried clearing the permissions in the Data Source Settings, but that did not help.

The REST URL works fine in Postman. Any suggestions?

hi @mscherotter 

Clear the Secure Sockets Layer (SSL) state. To do this, follow these steps:

1. In Internet Explorer, click Tools, and then click Internet Options.
2. Click the Content tab, and then click Clear SSL state.

Regards,

@mscherotter , Check this topic in the past, very old and not marked as a solution. But few approaches have been discussed there -https://community.powerbi.com/t5/Power-Query/How-to-Authenticate-to-a-REST-API-with-basic-Authentica...

@mscherotter When you test, are you using http or https?
