Grafana, F-5 and Azure AD authentication configuration

Hello, I have a VM installed grafana 8.x (without https certificate) and I have a F-5 that publishes the vm to the Internet and puts the https layer by dumping the outer port 443 to the inner port 3000, when I try to integrate it into Azure AD with the Azure AD OAuth2 authentication system I find that once the user has authenticated it does not show the grafana website, as much as I check I can not find the error, what step I had to leave?

In the web that I register in azure I put it like this, with a subdomain.

Thank you very much
