Trying to connect to use a (self cert) to an internal https url but get 'failed to verify certificate: x509'

[G0nz0uk]

Hello,

I have an internal URL on either of these that I need to show in Grafana via the Infinity json plugin:

URL
https://site.mydomain.com/nodes?format=json
or
https://192.168.200.243/nodes?format=json

The site has basic auth so just a username and password (at some point it will use LDAP)

I create an self certificate with the fqdn site.mydomain.com and added to our DNS servers and I can ping site.mydomain.com and get 192.168.200.243.

Now if I try in Grafana using the Infinity plugin I get:

error while performing the infinity query. error getting response from url https://site.mydomain.com/nodes?format=json. no response received. Error: Get "https://192.168.200.243/nodes?format=jsonhttps%3A%2F%2Fsite.mydomain.com%2Fnodes%3Fformat%3Djson": tls: failed to verify certificate: x509: cannot validate certificate for 192.168.200.243 because it doesn't contain any IP SANs

Please help, I'd love to get this working?

I was thing do I need to create a public fqdns and cert, but this is in dev and I just want to test this json works before I buy a proper name.

Using another JSON plugin on the Grafana site it works with that one:

Thanks
