Issue after installation of grafana

I have an issue occurs after installation,

Could not communicate with your OnCall API at http://engine:80. Validate that the URL is correct, your OnCall API is running, and that it is accessible from your Grafana instance

Please help

Hi @ahmed89,

Welcome to the :grafana: community support forums !! :slight_smile:

Can you please tell us how you installed Grafana OnCall (i.e. which documentation you followed)?

Also, did you install OnCall cloud OR OnCall OSS?
