Your Grafana doesn’t have connectivity to your identity provider (“oauth”) server. Check your network setrings. If you are using containers then keep in mind that each container has own localhost.

I have similar type of issue in which it is saying as “state mismatch”. Please help me to solve it.
I also want to know what should I pass in client_secret in grafana.ini file

I have created a virtual host auth.local and refer it in grafana, then it says no host found . please find the logs in grafana bellow:

Looks like the issue is some where else, the call is intercepted before its even made in my case with the same error message
