net::ERR_CERT_AUTHORITY_INVALID

Hello

I´m using an ASP.NET as a data source to Grafana, but every time I try to connect to it, I get the error “Failed to fetch:net::ERR_CERT_AUTHORITY_INVALID.” I´ve tried to connect to the same endpoint using postman, and I got no problems.

I´ve tried on both Chrome and EDGE browsers, but the issue persists.

I really appreciate any help you can provide.

How? Give us details about your connection attempt (redacting anything
sensitive, of course).

Is the error message from your browser, or is it from Grafana?

Trying to sum up all in one place the best I could find out until now

After installing the public for JSON connection to grafana JSON plugin for Grafana | Grafana Labs I am trying to test the connection, so:

1 - I developed a method in ASP.NET that return the code 200 for that endpoint
2 - I tested it using postman and the endpoint worked returning the wanted code 200

3 - I configured the Data Source in the locally installed grafana and tested the connection, giving me a fail to fetch error

4 - I went to the dev settings in the chrome browser, more specifically at the Network tab, and found this ( the connection fail)

“Failed to fetch:net::ERR_CERT_AUTHORITY_INVALID.” is the message when hovering the “failed”

Resuming, I can connect to the API from postman without problems, but when I try to connect from my locally installed grafana to my locally running API it retrieves the above-mentioned error. What can I do to make it work ?

I´ve already tried in the Microsoft EDGE browser too
