undefinedPowerBi to API SSL/TLS error

[rgouette]

I'm trying to connect to a Web Datasource for a REST API call.

I am using the Bearer Header, with token, taken from Postman(the API is known good)..

But when I try to connect, I get:

Ideas?

I see someone in 2019 post the same issue, with no follow-up resolution

Kind thanks,

Question: I'm seeing in places online that TLS 1.3 may not be compatible with PowerBi as far as authenticating..
Thoughts?

Thanks,
Rich

I just discovered the Custom Connector, which allowed me to gain access to  a number of things such as Functions, Gateways, Workspaces etc.. So far don't see my teams workspace, but I'll keep at it

Hi, @rgouette 

Thank you for sharing the issues you’ve encountered with us and for keeping us updated on your progress. Regarding your concerns, you might try the following steps:

1.Firstly, ensure that Power BI is using a supported TLS version (such as TLS 1.2).

Below are relevant screenshots from the documentation:

For further details, please refer to:

Deprecating TLS 1.0 and 1.1 support in Power BI | Microsoft Power BI Blog | Microsoft Power BI
 

2.Secondly, if the API uses a self-signed certificate, Power BI may not be able to verify it.

You could try disabling the relevant settings in the Desktop application:

For further details, please refer to:

Certificate revocation check, Power BI Desktop - Power BI | Microsoft Learn

3.Finally, here’s a link to similar issues that others have faced, which I hope will be helpful to you:
